Fort Worden Historical State Park is located in Port Townsend, Washington, on originally known as Fort Worden, a United States Army Coast Artillery Corps base constructed to protect Puget Sound from invasion by sea. Fort Worden was named after U.S. Navy Rear Admiral John Lorimer Worden, commander of during the famous Battle of Hampton Roads during the American Civil War. Constructed between 1898 and 1920, Fort Worden was one of the largest Endicott Period (1890-1910) forts to be built and a rare example of a post built according to the precepts of the Endicott Board on land not already occupied by an existing fortification. It was located within sight of a potential (if unlikely) enemy fortification, a British Royal Navy installation on Vancouver Island in Canada. The fort was designated a National Historic Landmark in 1976. History Fort Worden was an active United States Army base from 1902 to 1953. It was purchased by the State of Washington in 1957 to house a juvenile detention facility. In 1971, use was transferred to the Washington State Parks and Recreation Commission and Fort Worden State Park was opened in 1973. Strategic location In the 1890s, Admiralty Inlet was considered strategic to the defense of Puget Sound in that three forts—Fort Worden, Fort Flagler, and Fort Casey—were built at the entrance with their powerful artillery creating a "Triangle of Fire" to thwart any invasion attempt by sea. Fort Worden, on the Quimper Peninsula, at the extreme northeastern tip of the Olympic Peninsula, sits on a bluff near Port Townsend, anchoring the northwest side of the triangle. The three posts were designed to prevent a hostile fleet from reaching such targets as the Puget Sound Naval Shipyard and the cities of Seattle, Tacoma and Everett. The forts never fired a hostile shot, and many of the guns were removed during World War I for use in Europe; all remaining now-obsolete guns were scrapped during World War II. Subsequently, Fort Worden was used for training a variety of military personnel and for other defense purposes. Construction The oldest building on the post is Alexander's Castle, a brick residence built in 1883 by Reverend John Barrow Alexander (1850-1930) which pre-dates the military presence. A British citizen, Alexander was the rector of St. Paul's Episcopal Church in Port Townsend from 1882 to 1886, as well as Queen Victoria's British Vice Consul in Port Townsend and Tacoma from
