The first lighthouse in the state was erected in 1749 and the last in 1962 (ignoring automated towers erected later); the oldest surviving structure is the much-modified Poplar Point Light, although the tower now standing at Prudence Island Light was first erected at Goat Island in 1824. The tallest extant tower is that at Beavertail Light, though the focal plane of the Block Island Southeast Light is much higher on account of the bluffs upon which it sits.
