At the northern end of the Wassaw Beach, facing the ocean, are the ruins of Fort Morgan from the
Spanish–American War, built in 1898 by Second Lieutenant Henry Sims Morgan of the U.S. Army Corps of Engineers. The fort is made from cement and granite gravel, with small clam shells embedded in the walls. The ruins are slowly deteriorating as tidal forces and shifting sands have caused sections to crumble under their own weight. The tidal action of the beach leaves much of the ruins exposed some years and other years much of it appears to have been buried under several feet of sand. Sometimes the corroded remains of the bolts which held the two 4.7-inch rapid fire cannon mounts are clearly visible in their circular pattern located on either side of the main bunker. These two cannons were intended to defend Savannah against a possible approach by the Spanish via the Wilmington River. The fort was the largest single fortification built specifically for the Spanish–American War and was constructed by civilians under the guidance of the US Army Corps of Engineers. As the ruins are a prominent feature easily visible from other coastal islands to the north, the top of the bunker has an official USGS Survey marker embedded in the concrete roof. Since
Hurricane Irma in 2017 the surrounding beach has eroded, leaving the structure approximately 40 yards off of the beach at low tide. ==Airplane crash==
