The is located in
Fort Casey State Park near
Coupeville on
Whidbey Island , Washington.
In
1858 the
United States purchased 10 acres (40,000 m²) of land costing $400 for the location of the
Lighthouse . In 1890, with construction of the fort to protect
Admiralty Inlet , the light was relocated, relinquishing the building and site to the
U.S. Army . The original red wooden lighthouse was demolished to make room for soldiers and guns in Fort Casey.
The replacement lighthouse, constructed of
Brick and
Stucco , was built in
1903 . During its later occupancy by the Army, the lighthouse was used as a training facility for the
K-9 Dog Program .
The lens has been removed, and the 30 foot (9 m) tall lighthouse has since been restored by the Parks Commission. It is used as an interpretive center by a local non-profit group known as the Beachwatchers.
