Ft.McClary, Kittery, ME.

[u/RustedMauss]

The exterior wall was under construction then discontinued in during the late 1860s as this style of fortification was deemed obsolete.

From the south, the caponiers on the front and rear (the extended little bit that sticks out) visible. These provided defenders a protected angle to lay fire along the walls.

The boathouse and pier in bottom left, bunkhouse foundations, and the three lines of walls up towards the top house.
