Spring Point Ledge Light is located in South Portland, Maine. It is a fairly typical “spark plug” style lighthouse of the period, built on a cylindrical cast-iron caisson. The lighthouse was constructed in 1897 by the government after seven steamship companies stated that many of their vessels ran aground on Spring Point Ledge. Improvements were made to the lighthouse throughout the 20th century. It was electrified in 1934, and in 1951, a 900-foot breakwater made from 50,000 tons of granite was constructed in order to connect the lighthouse to the mainland. I took this shot while passing by on a whale watching boat.
