The wood lookout at Azicoos in Oxford County was built in 1910 as a wood house on a ledge.
A wood tower replaces it in 1917. A new wood tower, in a different location, went up in 1919.
A 24-foot steel tower replaced the wood structures in 1929.
From the tower, the watchman could see Katahdin, Kennebago, Saddleback, Baldpate, Bigelow and Boundary bald Mountains.
He also could see more than 25 bodies of water.
