The Haunted WW2 Sea Fort

Grain Fort was constructed in the 1860s to defend the mouth of the River Medway and Thames against the threat of French naval attack. It was designed to support both Grain Tower out at sea, built from 1848-55, and Garrison Point Fort at Sheerness. It was altered and upgraded during proceeding conflicts, including the First and Second World Wars, until it was decommissioned in 1956. After this, it was mostly demolished although remnants of the front of the fort can be seen today including its filled-in gun pits along the terreplein (upper surface) amongst a shrubbed coastal park and World War Two spigot mortar bases for use by the Home Guard. Underground, more substantial sections of the fort survive as two sets of subterranean tunnels, including the main magazine, caponiers, and an ammunition lift.
