Palmerston Fort - Slough Fort

Slough Fort is a small seven-gun Royal Commission fort built in the 1860s on the north of Medway, Kent near Allhallows-on-Sea. It is intact and being used as riding school stable.

It was built in 1867 as an arc of seven granite faced casemates. The seven 7in rifled breech loaders were designed to impede shipping on the Thames. By 1895, modifications had been done to the flanks and it was armed with two 9.2in and two 6in breech loaders on hydro-pneumatic disappearing mounting. The mountings were changed by 1905 and the fort was disarmed in 1912.
