A stone observation tower patterned after a medieval watch tower stands at the summit. It was designed by architect Ellsworth Storey and built by the Civilian Conservation Corps in 1936. The tower offers panoramic views of the surrounding islands, the Cascade Mountains, and many Canadian and American cities. On a clear day, the view encompasses locations as diverse as Mount Baker, Mount Rainier, Saturna Island, and the cities of Vancouver, and Victoria, British Columbia. Mount Constitution lies within the Moran State Park.
