Grain Fort

Grain Fort was built in the 1860s on the eastern end of the Hoo peninsula to control the entrance to the Medway, Kent, England.

All surface structures were demolished in the 1960s, so all that remains are underground passages.

Nearby is the 1855 Grain Tower Battery, an extensively remodelled East Coast type Martello Tower. Garrison Point Fort lies the other side of the Medway.
