Close your eyes and imagine Fort Casey as it must have been 100 years ago, filled with eager young soldiers, officers, mechanics and staff. Stand at the Admiralty Head lighthouse or in a cliff-side gun battery and scan the horizon, as the enlisted men must have done during World War I and II.
Fort Casey, Fort Worden and Fort Flagler together were known as the "Triangle of Fire," a trio of strategically placed fortifications defending the entrance to the Puget Sound at the turn of the 20th Century.
Constructed in the late 1800s, Fort Casey was equipped for defense and used as a training facility up to the mid-1940s. The fort houses a pair of rare 10-inch disappearing guns. While the guns were the height of technology in the early 1900s, improvements in warships and the advent of airplanes soon rendered them obsolete. Two additional 3-inch mounted guns are also on display in their original emplacements. You can explore these batteries to your heart's content.
So round up your family, friends and history buffs, and step back in time to Fort Casey Historical State Park. From the romantic 1903-vintage lighthouse, with its own interpretive center and gift shop, to the catacomb-like bunkers and batteries, this historic military fort is sure to ignite curiosity.
