Its brick walls are several feet thick at the bottom, tapering to about two feet thick at the top.HistorySapelo Island Lighthouse was built in 1820. It was designed and built by Winslow Lewis. It had fifteen Lewis lamps with 16in reflectors. In the 1850s, the tower was raised by 10ft and a fourth-order Fresnel lens was installed in 1854. The lens was removed during the Civil War. It was extensively repaired after an 1867 storm and relit in 1868. The tower was damaged by a strong hurricane in 1898.A pyramidal 100ft skeletal tower lighthouse with a third-order Fresnel lens was built in 1905. This tower was dismantled and relocated in 1934 to South Fox Island, Michigan.
