The "Dark Arch"
Originally an open courtyard, Bastion A was roofed over, probably in the 1870's to accommodate new artillery-15-inch Rodman Guns. The new space was divided into an indoor drill hall, a powder magazine and a storage area for wagons and gun carriages. Construction was carefully routed around a well (now blocked off). During the Second World War the area became a fort favorite: a recreation hall where soldiers on a cold, isolated post could take their minds off training and war. Today the "Dark Arch" leads to a murky passageway to the exterior of the fort.
