In 1858, the U.S. government purchased ten acres of land costing $400 for the construction of Admiralty Head Lighthouse. In 1890, the army took over the premises. It named its garrison "Fort Casey" in honor of Brigadier General Thomas Lincoln Casey, the last U.S. Army chief of engineers. At that time, Fort Casey, in union with Fort Worden and Fort Flagler, was said to comprise a "triangle of fire" guarding the entrance to Puget Sound.

When the fort was constructed, the old lighthouse had to be moved. A new lighthouse was built on the present site in 1903. Today the Admiralty Head Lighthouse at Fort Casey serves as a historic landmark and interpretive center. The park was incorporated into Ebey's Landing National Historic Reserve in 1980.
