Inscription. Portsmouth Harbor was protected by underwater mine fields during both wars. During World War II, this protection was supplemented by an anti-submarine net which stretched across the mouth of the harbor from nearby Fort Stark to Fort Foster in Kittery Maine. A coast guard picket boat opened a gate in the net to allow ships to pass through to the naval shipyard.

This building, fortified with steel window shutters and steel-plated doors, was built in 1901 as a store house for underwater mines. By 1908, mine casements were located here at Fort Constitution, at Fort Stark, and Fort Foster as part of the First Mine Command.

Today the Mines Building is used as a sea water research laboratory by the University of New Hampshire.
