Reasons for Designation

Martello towers are gun towers constructed to defend the vulnerable south eastern coast of England against the threat of ship-borne invasion by Napoleonic forces. Built as a systematic chain of defence in two phases, between 1805-1810 along the coasts of East Sussex and Kent, and between 1808- 1812 along the coasts of Essex and Suffolk, the design of martello towers was based on a fortified tower at Mortella Point in Corsica which had put up a prolonged resistance to British forces in 1793. The towers take the form of compact, free-standing circular buildings on three levels built of rendered brick. The towers of the south coast were numbered 1-74 from east to west, while those of the east coast were identified by a system of letters (A-Z, and then AA-CC) from south to north. Although they exhibit a marked uniformity of design, minor variations are discernible between the southern and eastern groups and amongst individual towers, due mainly to the practice of entrusting their construction to local sub-contractors. Most southern towers are elliptical in plan, whilst the eastern group are oval or cam-shaped externally, with axes at the base ranging between 14.4m by 13.5m and 16.9m by 17.7m. All are circular internally, the battered (inwardly sloping) walls of varying thicknesses, but with the thickest section invariably facing the seaward side. Most stand to a height of around 10m. Many martello towers are surrounded by dry moats originally encircled by counterscarp banks, and/or have cunettes (narrower water defences) situated at the foot of the tower wall. The ground floor was used for storage, with accommodation for the garrison provided on the first floor, and the main gun platform on the roof. The southern towers carried a single 24 pounder cannon, whilst the eastern line carried three guns (usually a 24 pounder cannon and two shorter guns or howitzers). Three large, circular ten- gun towers known as redoubts were also constructed at particularly vulnerable points, at Dymchurch, Eastbourne and Harwich. All three survive. As the expected Napoleonic invasion attempt did not materialise, the defensive strength of the martello tower system was never tested, and the tower design was soon rendered obsolete by new developments in heavy artillery. Many were abandoned and fell into decay or were demolished during the 19th century, although some continued in use into the 20th century as signalling or coastguard stations and a few saw use as look out points or gun emplacements during the two World Wars. Of the original 74 towers on the south coast, 26 now survive, and of the 29 on the east coast, 17 now survive. Those which survive well and display a diversity of original components are considered to merit protection.

Martello tower no 55 survives well, and retains many of its original components. It is one of the surviving examples of a series of low-lying towers, designed to defend a specific stretch of coastline and, as such, the tower contributes towards our understanding and appreciation of the martello tower system. Its subsequent use for both semaphore communication and wireless telegraphy, and its later conversion to a Battery Observation Post during World War II, signifies the continued, strategic importance of this position well into the 20th century.


The monument includes a martello tower and a World War II battery observation post, situated at the head of a shingle beach at Normans' Bay, to the south east of Bexhill. The tower, which is Listed Grade II, lies about 3km north east of its surviving neighbour (tower no 60), which has been converted into a private residence. The pair were constructed in 1805-6 as part of a long chain of low lying towers, spaced at 500m intervals, and designed to guard the vulnerable coastline around Pevensey Bay. The slightly elliptical, brick built tower measures up to approximately 13m in diameter, and rises to a height of about 10m. Its battered (inwardly sloping) walls, designed to deflect cannon shot, range in thickness from 1.6m to around 4m on the more vulnerable seaward side. Externally, the tower was rendered in a cement mortar to protect the outer skin of bricks, and much of this will survive beneath the modern render. The tower was constructed on three levels, with a thick central column rising between the basement and the top of the tower, from which springs the barrel vaulted first floor ceiling that supports the gun platform on the roof. A first floor doorway on the northern, landward side provided the original access into the tower, and was reached from the ground by a retractable ladder. This was later blocked and replaced by a ground floor entrance beneath it. The first floor was divided into three rooms by wooden partitions, two of which survive, and provided accommodation for the garrison of 24 men and one officer. Two fireplaces heated the rooms, and there were windows to the east and west. The western window was enlarged at a later date, and the eastern window adapted to form a gun loop during World War II. The tower has been pierced by several further openings. Photographic evidence suggests that, by the early 1900s, the western window opened onto a balcony, attached to the seaward side of the tower. The remains of concrete steps, and a curving concrete ramp, survive at the base of the tower below the window. The balcony has been removed, although the cast iron brackets remain. Access to the ground floor was originally by way of a trap door near the original first floor entrance, leading down through the wooden floor, which is suspended on heavy timber joists radiating from the central brick column. A spiral staircase was later inserted into the thickness of the wall to improve access to the ground floor level. The ground floor was used to store ammunition and supplies, and provision for these included a single, vaulted magazine, partly recessed into the thickness of the outer wall. Rainwater collection tanks were installed beneath the floor to supplement the water supply, and air vents, linking the ground and first floors, were set into the thickness of the walls. Safety features include a surviving carefully designed lantern window, in which the lamp was separated from the magazine by panes of glass to minimise the risk of explosion. The gun platform is reached from the first floor by an original, internal stone staircase, constructed within the thickest part of the tower wall. The circular roof space was originally designed to accommodate a 24-pounder cannon, which had a range of around 1.5km and could be turned through 360 degrees. The cannon was mounted on a wooden carriage, supported on a central pivot, and was traversed on inner and outer iron running rails by a series of rope pulleys and iron hauling-rings set into the encircling parapet wall. The gun was removed during World War II, and replaced by a low, concrete Battery Observation Post, constructed within the roof space to provide information to an Emergency Battery at Normans' Bay. Further evidence for coastal defence during World War II, survives in the form of two anti-tank blocks, of unusual design, located close to the base of the tower; these are also included in the scheduling. During the 19th century, tower no 55 became one of four martello towers to be fitted with a semaphore machine, and in the early 1900s it was used for a series of wireless telegraphy experiments. The small, ruinous lean-to building, of concrete block construction, and its associated cistern, built against the north western side of the tower, are considered to be later 20th century additions. All modern fixtures and fittings and all modern material within the tower are excluded from the scheduling, although the structures to which they are attached are included. The lean-to and cistern is excluded from the scheduling, although the ground beneath it is included.
