Historical Background

Formerly a U.S. Coast Guard Artillery Fort established in the late 1890s, its operation was coordinated with those of Fort Worden and Fort Flagler.

In 1858 the United States purchased 10 acres of land costing $400 for the location of the Admiralty Head Lighthouse. In 1890, with construction of the fort, the light was relocated, relinquishing the building to the Army. In 1899, the Adjutant General's office officially named the garrison "Fort Casey" in honor of Brigadier General Thomas Lincoln Casey, the last Chief of Engineers, United States Army. During its later occupancy by the Army, the lighthouse was used as a training facility for the K9 dog program. It has been restored by the Parks Commission and presently is being used as an interpretive center. In 1980, Fort Casey was incorporated into the Ebey's Landing National Historical Reserve by the National Park Service.
