Guarding the narrowest point of the English Channel, Dover Castle is one of the largest and most powerful fortresses in England, nicknamed the 'Key to England'. Within its grounds stands a Roman lighthouse, the Pharos, one of the oldest standing buildings in Britain. From the famous White Cliffs of Dover medieval pilgrims took ship across the Channel to Calais to continue their journey to Rome, and the same crossing remains the gateway from England to the Continent today.

History
Henry II rebuilt the earlier stronghold from the 1180s, his engineer Maurice raising the great keep by 1189 at vast expense. In 1216 the garrison under Hubert de Burgh withstood a long siege by Prince Louis of France during the First Barons' War. Between 1797 and 1805 tunnels were cut into the chalk beneath the castle to house troops against Napoleon, and from these same tunnels Vice-Admiral Ramsay directed Operation Dynamo, the evacuation from Dunkirk, in May 1940.
Myth & legend
The chronicler Matthew Paris called Dover 'the very key of England' after Hubert de Burgh's garrison held the castle against Prince Louis of France in the great siege of 1216. Within the walls, the Roman pharos that once guided galleys across the Channel now serves as bell tower to the church of St Mary in Castro.
Geology
The White Cliffs are pure Late Cretaceous chalk, built from the microscopic calcite plates of planktonic algae that rained onto a sea floor 70 to 90 million years ago, with dark seams of flint tracing the bedding. Here the chalk ridge of the North Downs meets the sea, and the same ridge continues beneath the Strait of Dover to rise again in the chalk country of northern France.
Wildlife & nature
The chalk grassland on the cliffs below is grazed by Exmoor ponies and Dexter cattle, and its horseshoe vetch supports Adonis and chalkhill blue butterflies alongside pyramidal and fragrant orchids in June. Fulmars and kittiwakes ride the updraughts off the white cliffs, skylarks sing over the downland, and peregrines hunt the chalk face.
The view
The medieval Great Tower and its rings of walls crown Castle Hill high above the Channel, with the Roman Pharos beside the Saxon church of St Mary in Castro and ferries crossing far below.
Photography
From the seafront or the Western Heights, catch the castle stacked above the town; on site, shoot the Pharos and St Mary in Castro together, and save clear days for views towards the French coast.
When to visit
May to September gives the best Channel visibility and sea light; summer weekends and school holidays are busiest; autumn brings dramatic skies, and wind is a constant on the heights.
Getting there
Walkers arrive over the North Downs on the final English stage; from Dover Priory station it is a stiff uphill walk to the entrance, with local buses and taxis sparing the climb before the ferry to Calais.
Where to stay
Dover has harbour-facing hotels, guesthouses and B&Bs suited to an early ferry; many pilgrims spend their last English night here, with Canterbury an easy fallback by train.
Food & water
Carry water up Castle Hill; cafes on site and in the town below bracket the climb, and refill points are scarce along the exposed cliff-top paths either side of the port.
Safety
On the White Cliffs paths keep well back from the edge — the chalk is crumbly and undercut, and winds gust hard on the top. Spiral stairs in the keep and tunnels are steep and dim. In an emergency dial 999 or 112 and ask for the Coastguard for cliff emergencies; NHS 111 for non-urgent advice.
Accessibility
The site is steep, with cobbles, grass slopes and long distances between areas; the Great Tower involves spiral stairs, and the wartime tunnels are visited on guided walks with steps.
Visitor tips
Allow half a day before the crossing; combine the castle with a cliff-top walk towards South Foreland, and ask at your lodging or the town museum about a final English stamp for the credential.
The guide, in full
The written guide to this site.
The land runs out at Dover. You come over the last of the North Downs, the chalk track tips downhill, and suddenly there is nothing ahead but grey-green water and, on a clear day, a pale line on the horizon that is France. High on the eastern heights above the town stands the fortress that has watched this crossing for nine centuries, the castle the chronicler Matthew Paris called the very key of England. Climb Castle Hill and go first to the oldest thing here, because it may surprise you. Beside the Saxon church of St Mary in Castro rises the Pharos, an octagonal tower of Roman flint and tile raised as a lighthouse to guide galleys across the Channel not long after Rome took Britain. It is among the oldest standing buildings in the country, and for centuries it has served as the church's bell tower. A Roman signal fire turned to Christian use is a fair summary of this whole road. The great square keep is the work of Henry the Second. From the eleven eighties his engineer Maurice raised it at enormous expense, finishing by eleven eighty-nine, and ringed it with concentric walls that made Dover the most modern fortress in western Europe. It was tested in twelve sixteen, when Prince Louis of France invaded during the war of the barons and besieged the castle for months. Hubert de Burgh and his garrison held out, mining and countermining beneath the northern gate, and the French were turned back. The key stayed in English hands. There is a second castle underfoot. Between seventeen ninety-seven and eighteen oh five, with Napoleon massing across the water, tunnels were driven into the chalk to barrack thousands of troops. They were opened again in the twentieth century, and in May nineteen forty, from a chamber cut in this cliff, Vice-Admiral Bertram Ramsay directed Operation Dynamo, the evacuation of a third of a million soldiers from the beaches of Dunkirk by every vessel that could be found. Stand at a tunnel mouth, look down at the harbour, and the geography explains itself. Then give the cliffs your attention, because they are the reason for everything else. This is pure Late Cretaceous chalk, built from the microscopic calcite plates of drifting algae that rained onto a sea floor between seventy and ninety million years ago, threaded with dark seams of flint. The ridge you have been walking since Canterbury dives beneath the strait here and rises again in the cliffs of northern France, so the country ahead is quite literally a continuation of the country behind. On the grassland below, Exmoor ponies and Dexter cattle graze turf rich in horseshoe vetch, which feeds Adonis and chalkhill blue butterflies, and pyramidal and fragrant orchids come up in June. Fulmars and kittiwakes ride the updraughts, skylarks sing overhead, and peregrines hunt the white face. Keep well back from the edge, because the chalk is crumbly and undercut and the wind gusts hard on the top. Medieval pilgrims came down this hill to take ship for the French shore, and you are about to do the same. Ask at your lodging or the town museum for a final English stamp in your credential, then sleep above the harbour. In the morning the sea will carry you over, and the road picks up again on the far shore.
