Grovers Cliff is a shoreline escarpment at Broad Sound near the Port of Boston and by extension, the landform extending into the sea (headland) that is the "Highlands" section of Winthrop, Massachusetts. The headland is at the north end of Winthrop Beach and is noted for an 1847 survey station, WWI & II fortifications and a Cold War nuclear bunker used by the US Army, USCG, USN, USAF, and FAA as Fort Heath, the eponym of the landform's current apartment complex.
