Built in 1767 with money raised from a series of lotteries in Philadelphia, the lighthouse was made of stone brought down from the Brandywine River north of Wilmington, Del., near the Pennsylvania border.
The tower was 26 feet in diameter, 6 feet thick at the base, 69 feet, 3 inches tall, and 17 feet, 6 inches in diameter and 3 feet thick at the top. It was built on the north side of the Great Dune, 46 feet above sea level, to obtain additional height.
Because the dune moved 3 to 5 feet a year, it eventually claimed the lighthouse. When it collapsed, it is said many local residents went to the site to collect the stone for fireplaces and chimneys.
