Fort Columbia Guardian of the great river Part 2

Fort Columbia is one of three fortifications built by the United States to guard and defend the mouth of the Columbia river. Erected during the period when wars were fought only on the ground and on the sea, it was declared obsolete after World War II.
In 1950 the Fort Columbia Military Reservation was transferred to the State of Washington to be preserved as Fort Columbia Historical State Park.
Virtually intact except for it's armament, Fort Columbia remains in appearance a typical coast artillery post of the late 1890's and early 1900's.
This video details the history of the fort and how it functioned including rare footage of the disappearing guns being fired.
