Fort Casey: Nestled on Whidbey Island - Home to 10-inch Guns

Built in 1897 under the careful gaze of Brigadier General Thomas Lincoln Casey, Fort Casey on Whidbey Island, Washington, was designed to thwart seaborne invasions as part of a triangular defense strategy. In 1901, the fort's 10-inch guns began to roar, but the nightmare of the airplane's invention in 1903 turned Fort Casey into an easy aerial target. As World War I loomed, most of the fort's arsenal was removed. However, a few returned home, only to be sent off again during World War II. But two 10-inch guns took a vacation to the Philippines in the 1960s. After a life of adventure, they returned to Fort Casey and evaded the scrapyard during World War II. Today, Fort Casey is a peaceful 999-acre marine camping park.
