Description

Browndown Battery, built around 1888 or 1889, is a structure made of brick and concrete designed to accommodate two large guns and a control point on the west side. The concrete front of the gun emplacements slopes upwards to the edge of the V-shaped gun pit. Beneath the rear of each platform, there is ground floor accommodation, with a central ammunition store that has a more heavily protected roof. Although the battery is incomplete and in a state of dereliction, many detailed features remain, including steps, cupboards, channels, metal fixtures, and railings, which indicate the scale and type of armament that was once present. The south face, facing the fleet anchorage, is protected by a sloping earthwork, while the north inner side features a yard bordered by a high brick wall on its northern boundary.

Local climate

Browndown Battery receives an average of 800 mm of rain a year. This makes it drier than 54% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 74% of listed buildings.

It experiences an average of 20 freeze-thaw cycles a year, fewer than 79% of listed buildings. Of these, 8 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.

Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
