Slough Fort
A Victorian artillery fort on your doorstep
Slough Fort is a small D-shaped artillery fort just inland of the seawall in Allhallows, built in 1867 as part of the Palmerston coastal defences. Seven granite-faced casemates faced down the Thames, originally armed with 7-inch rifled breech-loading guns and upgraded in the 1890s to disappearing-mount 9.2-inch and 6-inch guns to impede enemy shipping heading up the estuary toward London.
From garrison to listed monument
The army left in 1920 and sold the fort in 1929, after which it had several civilian uses — including a brief stint as a small zoo. Today it's a Grade II listed monument in private ownership and the casemates have been adapted as stables. It's occasionally opened for tours and heritage open days — worth watching local listings if you're a history buff.
