The Tuscania Monument on Islay Island; American Monument on Oa

From the Welcome to Islay site.

The American Monument sits atop a 429-foot high cliff on the Oa Peninsula and was erected in 1920 by the American Red Cross.  It was designed by architect Robert Walked and commemorates the loss of two troopships, the Tuscania and Otranto in 1918.

It overlooks the exact spot where the Tuscania was sunk and is built in the shape of a lighthouse.  You can see it from most parts of the island of Islay.
