Dymchurch is a village and civil parish in the Folkestone and Hythe district of Kent, England. The village is located on the coast five miles (8 km) south-west of Hythe, and on the Romney Marsh. History The history of Dymchurch began with the gradual build-up of the Romney Marsh. New Hall was rebuilt in 1575 after an earlier wooden structure was destroyed in a fire. It was used as a court room for the Romney Marsh area. The head magistrate was known as Leveller of the Marsh Scotts. It was there that the so-called Scot tax was introduced, levied on residents to fund maintenance of the sea wall. Those directly outside the boundaries and thus not eligible for the tax were said to have got away "scot free". Residents with land were required to grow thorn bushes for building of the wall, as thorn twigs were believed impervious to sea water. Failure resulted in an ear being cut off. During the 17th and 18th centuries, smuggling was rife all along the south-east coast of England. Due to its remote location, Romney Marsh and the surrounding areas were amongst the busiest locations for illicit trade. This inspired Russell Thorndike to set his Doctor Syn smuggling novels in Dymchurch. Every two years a celebration of the novels is held, usually on August Bank Holiday. Dymchurch played a significant rôle in the Anglo-French Survey (1784–1790), which linked the Royal Greenwich Observatory with the Paris Observatory using trigonometry. There were two baselines for the English part of the survey, on Hounslow Heath and on Romney Marsh. The Romney Marsh base-line extended from Ruckinge to High Nook, on the sea-wall near Dymchurch. Dymchurch Martello towers Several Martello towers were built in the nineteenth century as part of an Empire-wide coastal defence programme: most have since fallen into the sea or become dilapidated. Tower 23 was restored externally in the early 1970s and is currently a private residence. Tower 24 has undergone renovation and using Tower 23 used as a guide: in 1969 it became the first Martello tower to be opened to the public and remains as a museum of Martello Towers, owned by English Heritage. Tower 25 is possibly the only empty tower that is regularly maintained.
