Martello Tower Number 25

Martello Tower Number 25 is a Grade II listed building constructed in 1806. This brick tower, which is covered in plain render, is circular and slightly tapers, standing about 30 feet high. The walls are reported to be between 5.5 and 6 feet thick. It features a renewed shallow domed roof that is surrounded by a projecting cement-rendered coping.

On the exterior, there are two small 20th-century casement windows, one located on the north side and the other on the south side, both with sills approximately 12 feet above the ground. Additionally, there are two small ventilation grilles near the base of the tower. A vertical door with a proud architrave and a segmental head is situated on the west side, with a sill about 10 feet up. Below this door, there is a T-shaped recess with a surround that continues from the door's architrave. A plaque is positioned above the doorway. At the time of the re-survey, there were no external steps, and a 20th-century door leads to the ground floor. The interior of the tower has been gutted.

This tower is part of a series built in 1806 as gunposts to defend against a potential Napoleonic invasion and is located immediately behind the sea wall. It is in proximity to Martello Tower No. 24 on High Street and Martello Tower No. 23 on Hythe Road.
