The Marblehead lighthouse was built in 1821 by William Kelly. The lighthouse took 11 weeks to build with the help of 2 other workers. The first lighthouse keeper was Benajah Wolcott. After Benajah, the lighthouse was kept by Ida Lewis – the first female lighthouse keeper in the United States. The lighthouse has had sixteen keepers in all. The US Coastguard is now responsible for the maintenance of the beacon.
