Battery Cameron

Battery Cameron was one in a chain of fortifications in the Civil War Defenses of Washington, D.C., also known as the "Fort Circle".

The battery included two 100-pound Parrott rifles, placed in such a way as to sweep Aqueduct Bridge, and Virginia beyond.

Its neighbors are the German Embassy (to the south), and George Washington University's Mount Vernon Campus (to the north).

Underneath Battery Cameron is a facility administered by the DC Water and Sewer Authority (WASA) called the "First High Service Reservoir".

[1] Robert Hanssen, the former FBI agent who spied for Soviet and Russian intelligence agencies until 2001, used the utility pole on the corner of Foxhall and Whitehaven, just outside the fence of the reservoir (formerly known as Battery Cameron) as a signal site.
