Summary of Monument
A 748m length of the Royal Military Canal from Scanlon’s Bridge to Town Bridge.
Reasons for Designation
The Royal Military Canal was a massive coastal defence work constructed between 1804 and 1809. Its purpose was to separate the expected landing and deployment of Napoleon's troops upon the coast of Romney Marsh and Walland Marsh from the interior of the country. The Government initially considered flooding the marsh but favoured the canal, which was the idea of Lt. Col. Brown, the Assistant Quartermaster-General. He carried out a survey and work commenced in 1804 at the height of the invasion scare, with John Rennie as consulting engineer (until 1805). The canal ran a total of about 28 miles from Shorncliffe Camp via Hythe inland to Appledore, to join the Eastern River Rother at Iden lock, from where it became part of first the Rother and then the River Brede, turning into a canal again from Winchelsea to Cliff End on the coast. Excavated earth formed the banquette and parapet on the landward side of the canal and behind this was an army supply route, the Royal Military Road. On the opposite side were the tow path and wharves. It also included a back and a front drain. The canal and parapets were so built that gun positions could be provided at the end of each length to flank the crossings. However by the time the canal was completed in 1809, the threat of invasion had passed, following Napoleon’s defeat at the Battle of Trafalgar, and it was to some extent obsolete. In 1810, the canal was opened for public use and tolls were also collected for use of the Royal Military Road. In the later 19th century public use declined. The last toll was collected at Iden Lock in December 1909. Today Iden lock is a sluice, so the main part of the canal is isolated. The eastern section of the canal is still in use for pleasure boats.
The Royal Military Canal was an important element in the Napoleonic defences of south-east England and is the only military canal in the country. It is a unique defensive work that bears significant testament to a period when modern Britain faced the most serious threat of invasion prior to the major conflicts of the 20th century.
Despite some disturbance and development, the 748m length of the Royal Military Canal from Scanlon’s Bridge to Town Bridge survives relatively well. It will contain archaeological information relating to its construction and use.
This record was the subject of a minor enhancement on 7 August 2014. The record has been generated from an "old county number" (OCN) scheduling record. These are monuments that were not reviewed under the Monuments Protection Programme and are some of our oldest designation records.
The monument includes a length of the Royal Military Canal, an early 19th century defensive work, situated on low-lying ground in Hythe. It runs about 85m ENE from Scanlon’s Bridge before turning ESE for 363m then curving to the east for the remaining 300m.
The length of canal is water-filled and the parapet, a bank on the north side, survives in places. Partial excavation in 1992-3 at Dymchurch Road Bridge identified elements of the earlier 1809 and 1813 bridges.
