Château de Joux

Rising on a crag above the Cluse de Pontarlier, the Château de Joux has guarded the narrow Jura pass between France and Switzerland for a thousand years. Successive generations fortified it, and it was completed by the engineer Vauban; later it served as a state prison. The fortress commands the gorge through which the Via Francigena threads its way up toward the Swiss border, a strategic gateway on the road to the Alps.

History

The lords of Joux raised the first wooden fort in the 11th century, rebuilding it in stone as tolls from the pass enriched them; in 1454 it passed to Philip the Good, Duke of Burgundy. France acquired it in 1678 and Vauban modernised the defences in 1690. As a state prison it held Mirabeau and the Haitian leader Toussaint Louverture, who met his end here in April 1803; the young engineer Joffre gave the fort its final form in 1879-81, and it now houses an arms museum.

Myth & legend

Legend tells of Berthe de Joux who, believing her crusader husband Amaury III fallen in the Holy Land, gave her heart to a young knight. On his return Amaury shut her for years in a cell too small to stand upright in; freed at last by her son, she ended her days in penitence at Montbenoît Abbey.

Geology

The castle crag overlooks a classic Jura cluse, a steep-sided gorge cut across the grain of the mountains through the Larmont anticline of folded Jurassic limestone. The Jura is a young fold belt, rucked up ahead of the Alps, and its long parallel limestone ridges could only be crossed where rivers had sawn such transverse gaps, which is why this narrow pass carries the road.

Wildlife & nature

The limestone walls of the cluse hold peregrine falcons and crag-nesting birds, with dry grassland and ravine woodland on the slopes and marshy hollows in the valleys either side. All around stand the Jura's great silver fir and spruce forests, where roe deer, chamois, black woodpeckers and crossbills are at home.

The view

The fortress stacks five successive walls up a limestone crag above the Cluse de Pontarlier, with Fort Malher on the facing cliff and the road to Switzerland threading the gorge below.

Photography

The Fer a cheval viewpoint above the cluse gives the classic composition of castle, twin forts and gorge; afternoon light models the crag, and autumn mist in the valley adds real drama.

When to visit

June to September is the dependable season in the high Jura; spring and autumn bring mist and sudden cold; winter snow transforms the crag but leaves paths icy at over 900 metres.

Getting there

The castle stands about five kilometres from Pontarlier above the village of La Cluse-et-Mijoux; walkers pass through the cluse on the way to the Swiss border, and taxis or local buses run from town.

Where to stay

Base yourself in Pontarlier, which has hotels, gites and pilgrim-friendly lodging; a handful of chambres d'hotes sit in the villages of the cluse itself.

Food & water

Carry water, as the climb to the castle has no refill points; cafes in La Cluse-et-Mijoux and Pontarlier cover you before and after the visit.

Safety

A gorge-side fortress: steep stairs, cliff-edge viewpoints and icy surfaces in winter. Keep to the visitor routes. In an emergency dial 112.

Accessibility

Visits mean ramps, stairs and uneven cobbles through five successive enceintes on a crag, with long flights of steps inside; the viewpoint across the gorge is the easier alternative.

Visitor tips

Combine the castle with the Fer a cheval viewpoint loop from Pontarlier; guided visits tell the story of the fortress and its prisoners, including Toussaint Louverture, once held here.

You are standing in a gap in the mountains barely wide enough for a road, a river and a railway, and above you a castle is climbing the sky. Five walls, one behind another, stack up the limestone crag, with Fort Malher glowering back from the opposite cliff. For a thousand years this narrow slot has funnelled every traveller bound for the Alps beneath that rock. It has counted merchants, soldiers and pilgrims. It has held a revolution's leader in chains, and a wife whose story still chills the valley.

Geology decided history here. The Jura is a young fold belt, rucked up ahead of the rising Alps, its beds of limestone bent into long parallel waves that are all but impassable, except where a river has sawn a gorge clean across the grain. Such a gorge is called a cluse, and this one, the Cluse de Pontarlier, cuts straight through the Larmont anticline, so everyone bound for Switzerland and the passes has squeezed through the same few hundred metres of valley floor. The lords of Joux raised a wooden fort above it in the eleventh century and grew rich on tolls from the road, rebuilding in stone as the money came in. In 1454 the castle passed to Philip the Good, Duke of Burgundy; France took it in 1678, Vauban modernised the defences for artillery in 1690, and a young engineer named Joffre, later a marshal of France, gave the fortress its final shape between 1879 and 1881.

Now, look for four things as you explore. First, the five successive walls themselves; climb from gate to gate and feel how each ring is one age's answer to the age before it. Second, from the ramparts, the cluse below, with road, river and railway braided through the slot and Fort Malher on the facing cliff completing the lock. Third, the arms museum under the old vaults, centuries of weapons gathered in a fortress that saw most of them come and go. And fourth, the wild Jura all around: peregrines nest on the limestone walls of the gorge, and the silver fir and spruce forests beyond hold roe deer, chamois, black woodpeckers and crossbills. If the climb is not for you, the Fer à cheval viewpoint above Pontarlier gives you castle, twin forts and gorge in a single sweep, best in afternoon light.

Cold, high and remote, Joux made a formidable state prison. The orator Mirabeau was locked up here by his own father. And the fortress received its most famous prisoner from across an ocean: Toussaint Louverture, the general who had led the Haitian revolution. He was carried over the sea in chains and held in a cell above the gorge through a bitter Jura winter, a man of the Caribbean shut in the mountain cold, and there, in April 1803, he died. The guided visits still tell his story, and his cell is the quietest room on the mountain.

Older still is the tale of Berthe de Joux. Believing her crusader husband Amaury fallen in the Holy Land, she gave her heart to a young knight. Then Amaury came home. He shut her away for years in a cell too small to stand upright in, and when her son at last set her free, she ended her days in penitence at the abbey of Montbenoît. So the story is told, and the stones do nothing to soften it.

Keep to the visitor routes on the steep stairs and cliff-edge viewpoints, then take the road on through the gap, past the last French farms towards Jougne and the Swiss border. Look up once more before the crag slides out of sight: five walls against the sky, still counting everyone who passes. Buon cammino.

Château de Joux: Fünf Mauern gegen den Himmel

Sie stehen in einer Lücke im Gebirge, gerade breit genug für eine Straße, einen Fluss und eine Eisenbahn, und über Ihnen klettert eine Burg in den Himmel. Fünf Mauern, eine hinter der anderen, staffeln sich den Kalkfelsen hinauf, und von der gegenüberliegenden Wand blickt Fort Malher herüber. Seit tausend Jahren zwingt dieser schmale Schlitz jeden, der in die Alpen will, unter jenen Fels. Er hat Kaufleute gezählt, Soldaten und Pilger. Er hat den Anführer einer Revolution in Ketten gehalten und eine Ehefrau, deren Geschichte dem Tal bis heute kalt den Rücken hinunterläuft.

Die Geologie hat hier die Geschichte entschieden. Der Jura ist ein junges Faltengebirge, vor den aufsteigenden Alpen zusammengeschoben, seine Kalkbänke zu langen parallelen Wellen gebogen, die kaum zu überwinden sind, außer dort, wo ein Fluss eine Schlucht quer durch die Falten gesägt hat. Ein solcher Durchbruch heißt Cluse, und dieser hier, die Cluse de Pontarlier, schneidet mitten durch die Larmont-Antiklinale. Wer in die Schweiz und zu den Pässen wollte, musste sich also durch dieselben paar hundert Meter Talboden zwängen. Die Herren von Joux setzten im 11. Jahrhundert eine hölzerne Feste darüber und wurden reich an den Zöllen der Straße, und wie das Geld kam, bauten sie in Stein weiter. 1454 fiel die Burg an Philipp den Guten, Herzog von Burgund. Frankreich nahm sie 1678, Vauban rüstete die Werke 1690 für die Artillerie um, und ein junger Ingenieur namens Joffre, später Marschall von Frankreich, gab der Festung zwischen 1879 und 1881 ihre endgültige Gestalt.

Vier Dinge sollten Sie hier suchen. Erstens: die fünf aufeinanderfolgenden Mauern. Steigen Sie von Tor zu Tor und spüren Sie, wie jeder Ring die Antwort eines Zeitalters auf das vorige ist. Zweitens, von den Wällen aus: die Cluse unter Ihnen, in der sich Straße, Fluss und Bahn durch den Schlitz flechten, mit Fort Malher an der Gegenwand, das das Schloss vollendet. Drittens: das Waffenmuseum in den alten Gewölben, Jahrhunderte von Waffen, versammelt in einer Festung, die die meisten davon hat kommen und gehen sehen. Und viertens: den wilden Jura ringsum. Wanderfalken nisten an den Kalkwänden der Schlucht, und in den Weißtannen- und Fichtenwäldern dahinter leben Rehe, Gämsen, Schwarzspechte und Kreuzschnäbel. Wenn Ihnen der Aufstieg zu viel ist, zeigt Ihnen der Aussichtspunkt Fer à cheval oberhalb von Pontarlier Burg, Zwillingsforts und Schlucht in einem einzigen Schwung, am schönsten im Nachmittagslicht.

Kalt, hoch und abgelegen gab Joux ein furchterregendes Staatsgefängnis ab. Den Redner Mirabeau ließ sein eigener Vater hier einsperren. Und seinen berühmtesten Gefangenen erhielt die Festung von jenseits eines Ozeans: Toussaint Louverture, den General, der die haitianische Revolution geführt hatte. In Ketten über das Meer gebracht, saß er einen bitteren Jurawinter lang in einer Zelle über der Schlucht, ein Mann der Karibik, eingeschlossen in die Kälte der Berge, und dort starb er im April 1803. Die Führungen erzählen seine Geschichte bis heute, und seine Zelle ist der stillste Raum auf diesem Berg.

Älter noch ist die Geschichte der Berthe de Joux. Im Glauben, ihr Mann Amaury sei als Kreuzfahrer im Heiligen Land gefallen, schenkte sie ihr Herz einem jungen Ritter. Dann kam Amaury heim. Er sperrte sie jahrelang in eine Zelle, in der sie nicht aufrecht stehen konnte, und als ihr Sohn sie endlich befreite, beschloss sie ihre Tage in Buße in der Abtei Montbenoît. So wird es erzählt, und die Steine tun nichts, um es zu mildern.

Bleiben Sie auf den ausgewiesenen Wegen, auf den steilen Treppen und an den Aussichtspunkten über der Wand, und nehmen Sie dann die Straße weiter durch die Lücke, an den letzten französischen Höfen vorbei Richtung Jougne und Schweizer Grenze. Schauen Sie noch einmal hinauf, bevor der Fels aus dem Blick rutscht: fünf Mauern gegen den Himmel, die noch immer jeden zählen, der vorbeikommt. Buon cammino.

Joux, il castello sulla gola

Siete in una gola di montagna larga appena per una strada, un fiume e una ferrovia, e sopra di voi un castello sta scalando il cielo. Cinque cinte di mura, una dietro l'altra, si arrampicano sulla rupe calcarea, mentre il forte Malher risponde torvo dalla falesia di fronte. Da mille anni questa fessura incanala ogni viaggiatore diretto alle Alpi sotto quella roccia. Ha contato mercanti, soldati e pellegrini. Ha tenuto in catene il capo di una rivoluzione, e una moglie la cui storia gela ancora la valle.

Qui è stata la geologia a decidere la storia. Il Giura è una catena giovane, corrugata davanti alle Alpi che si sollevavano, i suoi banchi di calcare piegati in lunghe onde parallele quasi invalicabili, tranne dove un fiume ha segato una gola di netto attraverso la piega. Una gola così si chiama cluse, e questa, la cluse di Pontarlier, taglia dritta l'anticlinale del Larmont, così che chiunque fosse diretto in Svizzera e ai valichi si è infilato nelle stesse poche centinaia di metri di fondovalle. I signori di Joux vi alzarono sopra un fortilizio di legno nell'undicesimo secolo e si arricchirono con i pedaggi della strada, ricostruendo in pietra man mano che il denaro arrivava. Nel 1454 il castello passò a Filippo il Buono, duca di Borgogna; la Francia lo prese nel 1678, Vauban ne modernizzò le difese per l'artiglieria nel 1690, e un giovane ingegnere di nome Joffre, futuro maresciallo di Francia, diede alla fortezza la sua forma definitiva fra il 1879 e il 1881.

Ora, quattro cose da cercare. Primo, le cinque cinte stesse; salite di porta in porta e sentite come ogni anello è la risposta di un'epoca all'epoca precedente. Secondo, dai bastioni, la cluse là sotto, con strada, fiume e ferrovia intrecciati nella fessura e il forte Malher sulla parete di fronte a chiudere la serratura. Terzo, il museo delle armi sotto le vecchie volte, secoli di armi radunate in una fortezza che le ha viste quasi tutte arrivare e passare. E quarto, il Giura selvatico tutto intorno: i pellegrini nidificano sulle pareti calcaree della gola, e le foreste di abete bianco e di abete rosso più oltre ospitano caprioli, camosci, picchi neri e crocieri. Se la salita non fa per voi, il belvedere del Fer à cheval sopra Pontarlier vi offre castello, forti gemelli e gola in un unico colpo d'occhio, al suo meglio nella luce del pomeriggio.

Fredda, alta e remota, Joux fu una prigione di stato formidabile. L'oratore Mirabeau vi fu rinchiuso da suo padre. E la fortezza ricevette il suo prigioniero più famoso da oltre oceano: Toussaint Louverture, il generale che aveva guidato la rivoluzione di Haiti. Fu trasportato per mare in catene e tenuto in una cella sopra la gola per un intero inverno del Giura, un uomo dei Caraibi chiuso nel freddo della montagna, e lì, nell'aprile 1803, morì. Le visite guidate raccontano ancora la sua storia, e la sua cella è la stanza più silenziosa della montagna.

Più antica ancora è la vicenda di Berthe de Joux. Credendo caduto in Terrasanta il marito crociato, Amaury, diede il suo cuore a un giovane cavaliere. Poi Amaury tornò. La rinchiuse per anni in una cella troppo bassa per starvi in piedi, e quando suo figlio infine la liberò, lei finì i suoi giorni in penitenza all'abbazia di Montbenoît. Così si racconta, e le pietre non fanno nulla per addolcirla.

Tenetevi ai percorsi di visita sulle scale ripide e sugli affacci a strapiombo, poi seguite la strada attraverso la gola, oltre le ultime fattorie francesi, verso Jougne e il confine svizzero. Alzate gli occhi un'ultima volta prima che la rupe scivoli fuori vista: cinque mura contro il cielo, che contano ancora chiunque passi. Buon cammino.

Joux, vijf muren tegen de lucht

Je staat in een spleet in de bergen die net breed genoeg is voor een weg, een rivier en een spoorlijn, en boven je klimt een kasteel de lucht in. Vijf muren, de een achter de ander, stapelen zich tegen de kalkrots op, met Fort Malher dat vanaf de klif aan de overkant terugkijkt. Duizend jaar lang heeft deze nauwe sleuf iedereen die naar de Alpen wilde onder die rots door geleid. Hij heeft kooplieden geteld, en soldaten, en pelgrims. Hij heeft de leider van een revolutie in de boeien gehad, en een echtgenote wier verhaal het dal nog altijd koud maakt.

De geologie heeft hier de geschiedenis bepaald. De Jura is een jong plooigebergte, opgestuwd vóór de rijzende Alpen uit, met kalksteenbanken die tot lange evenwijdige golven zijn gebogen en vrijwel onbegaanbaar zijn, behalve waar een rivier er een kloof dwars doorheen heeft gezaagd. Zo'n kloof heet een cluse, en deze, de Cluse de Pontarlier, snijdt recht door de Larmont-anticlinaal, zodat iedereen op weg naar Zwitserland en de passen zich door diezelfde paar honderd meter dalbodem heeft moeten wringen. De heren van Joux zetten er in de elfde eeuw een houten burcht boven en werden rijk van de tol op de weg; naarmate het geld binnenkwam, herbouwden ze in steen. In 1454 kwam het kasteel aan Filips de Goede, hertog van Bourgondië; Frankrijk nam het in 1678, Vauban maakte de verdediging in 1690 geschikt voor artillerie, en een jonge genieofficier met de naam Joffre, later maarschalk van Frankrijk, gaf het fort tussen 1879 en 1881 zijn definitieve vorm.

Zoek nu vier dingen terwijl je rondloopt. Ten eerste de vijf opeenvolgende muren zelf; klim van poort naar poort en voel hoe elke ring het antwoord van één tijdperk is op het tijdperk daarvoor. Ten tweede, vanaf de wallen, de cluse beneden je, met weg, rivier en spoor door elkaar gevlochten in de sleuf, en Fort Malher op de klif ertegenover dat het slot dichtdoet. Ten derde het wapenmuseum onder de oude gewelven, eeuwen wapentuig bijeen in een fort dat het meeste ervan heeft zien komen en gaan. En ten vierde de wilde Jura eromheen: slechtvalken broeden op de kalkwanden van de kloof, en de bossen van zilverspar en fijnspar daarachter herbergen reeën, gemzen, zwarte spechten en kruisbekken. Is de klim niets voor jou, dan geeft het uitzichtpunt Fer à cheval boven Pontarlier je kasteel, beide forten en kloof in één blik, het mooist in het middaglicht.

Koud, hoog en afgelegen als het was, werd Joux een geduchte staatsgevangenis. De redenaar Mirabeau werd hier door zijn eigen vader opgesloten. En zijn beroemdste gevangene kreeg het fort van de overkant van een oceaan: Toussaint Louverture, de generaal die de Haïtiaanse revolutie had geleid. Geboeid werd hij over zee gebracht en een bittere Jurawinter lang vastgehouden in een cel boven de kloof, een man van de Caraïben opgesloten in de bergkou, en daar stierf hij, in april 1803. De rondleidingen vertellen zijn verhaal nog altijd, en zijn cel is de stilste kamer van de berg.

Ouder nog is het verhaal van Berthe de Joux. In de veronderstelling dat haar man Amaury als kruisvaarder in het Heilige Land was gevallen, schonk ze haar hart aan een jonge ridder. Toen kwam Amaury thuis. Jarenlang sloot hij haar op in een cel waarin ze niet rechtop kon staan, en toen haar zoon haar eindelijk bevrijdde, sleet ze haar laatste dagen in boete in de abdij van Montbenoît. Zo wordt het verteld, en de stenen doen niets om het te verzachten.

Blijf op de steile trappen en bij de uitzichtpunten aan de rand netjes op de bezoekersroutes, en neem dan de weg verder door de spleet, langs de laatste Franse boerderijen richting Jougne en de Zwitserse grens. Kijk nog één keer omhoog voordat de rots uit het zicht glijdt: vijf muren tegen de lucht, die nog altijd iedereen tellen die passeert. Buon cammino.
