Shortly after World War II, Fort Stevens was deactivated as a military fort. The development of improved air power and guided missiles made coastal artillery forts such as Fort Stevens obsolete. By 1947, all of the guns were removed and much of the fort was turned over to the U.S. Army Corps of Engineers. The Corps used the area as their headquarters for maintenance activities at the mouth of the Columbia River. In 1975, Oregon State Parks leased the old fort area and are currently restoring and interpreting Fort Stevens.Welcome to WordPress. This is your first post. Edit or delete it, then start blogging!
