I have an eye (and heart) for lighthouses and my old post about the old Mackinac Point Lighthouse is one proof. While in Charleston, South Carolina, we visited the Sullivan Island Lighthouse. It is not the prettiest lighthouse I have seen but definitely one of the most unique lighthouses in America and that is a beauty itself. It resembles more an air traffic controller tower than a lighthouse, known for its unique triangular shape. It is also the only lighthouse known to be using an elevator instead of the typical spiral staircase found in most lighthouses.
