Dymchurch Martello Tower
Dymchurch Martello Tower, also known as Tower Number 24, stands as one of the best-preserved examples of the remarkable chain of defensive fortifications built along the southeastern coast of England during the Napoleonic Wars. Located on the seafront at Dymchurch in Kent, this squat, circular brick fortress is maintained by English Heritage and is open to the public, making it one of the few Martello towers in England that visitors can actually enter and explore. Its survival in such complete condition, complete with its original cannon mounted on a rotating carriage on the roof platform, is what makes it genuinely exceptional among its kind.
The tower was constructed between 1805 and 1808 as part of a massive national defence programme ordered in response to the credible threat of invasion by Napoleon Bonaparte's Grande Armée, which had massed along the French coast at Boulogne just a short distance across the Channel. The British government commissioned a chain of 103 Martello towers along the coasts of Suffolk, Essex, and Kent, supplemented by the Royal Military Canal that runs just inland from Dymchurch across the Romney Marsh. The design was inspired by a fortified tower at Mortella Point in Corsica that had famously resisted a British naval assault in 1794, impressing military planners with the defensive potential of a simple circular tower with immensely thick walls. Each tower was built to a broadly similar pattern — a squat, egg-shaped cylinder of brick with walls up to four metres thick on the seaward side, housing a garrison of one officer and around twenty-four men.
Tower 24 at Dymchurch is particularly noteworthy because it retains its original 24-pounder cannon, restored to working order and mounted on the roof in the manner it would have been during the Napoleonic period. The cannon sits on a traversing platform that allows it to be rotated through a wide arc to cover the beach and the approaches from the sea. The interior of the tower has been carefully restored to reflect its early nineteenth-century appearance, with the ground floor used for storage of ammunition and provisions, and the upper level serving as the living quarters for the garrison. The thick walls and vaulted ceilings create an atmosphere of genuine solidity and seriousness of purpose, and visitors can get a vivid sense of the cramped but purposeful conditions in which a small military detachment would have lived on constant watch.
Physically, the tower is an imposing presence on the flat Dymchurch seafront, its dark brick bulk rising above the sea wall with a characteristic no-nonsense solidity. The Romney Marsh stretching behind it is one of the most atmospheric and unusual landscapes in all of England — an extraordinarily flat, wide, light-drenched expanse of reclaimed land lying at or below sea level, crisscrossed by dykes and drainage channels, and grazed by the distinctive Romney sheep. The sea wall at Dymchurch is itself a significant engineering structure, holding back the English Channel from land that would otherwise flood, and walking along it beside the tower gives visitors a vivid appreciation of the relationship between this coastline and the constant threat of water. The sound environment is dominated by wind, gulls, and the distant surf.
The village of Dymchurch itself is a small, traditional seaside resort with a long sandy beach that is popular with families during the summer months. The Romney, Hythe and Dymchurch Railway — a narrow-gauge line running miniature steam locomotives and one of the most delightful heritage railways in England — passes through the village and connects it to Hythe in the north and Dungeness in the south, offering a charming and practical way to arrive. Nearby places of interest include the village of St Mary in the Marsh, associated with the writer E. Nesbit who is buried in its churchyard, and the extraordinary shingle headland of Dungeness with its nuclear power station, lighthouses, and Derek Jarman's famous cottage garden. New Romney, a few miles to the south, was once a Cinque Port of considerable significance before the sea retreated.
Dymchurch itself carries an unusual literary and folkloric heritage. The village was a major centre for smuggling during the eighteenth and early nineteenth centuries, and the fictional Vicar of Dymchurch is a central character in Russell Thorndike's series of Doctor Syn novels, in which a seemingly respectable clergyman leads a band of smugglers across the marsh by night. The novels drew on a very real and well-documented tradition of large-scale organised smuggling that operated throughout the Romney Marsh, with tunnels, hidden cellars, and networks of local informants and lookouts. The marsh's isolation and its maze of waterways made it ideal territory for moving contraband inland, and the revenue men were chronically outnumbered and outmanoeuvred.
English Heritage opens the tower seasonally, typically from late spring through early autumn, and entry is charged. The site is compact and can be thoroughly explored in an hour or two. Access inside the tower involves steep ladders between floors rather than conventional stairs, which should be noted by visitors with mobility considerations. The roof cannon platform affords excellent views across the beach and out to sea toward France on clear days, as well as inland across the remarkable expanse of the Romney Marsh. Parking is available in the village, and the site is well signposted from the main road.
