Block Island North Light was established to mark the entrances to Block Island Sound and Long Island Sound, as well as to warn mariners away from dangerous Sandy Point, extending a mile or so from the island. The first lighthouse built here in 1829 consisted of two lights on opposite ends of a building. Two years later, the schooner Warrior was wrecked at Sandy Point in a storm. Twenty-one people died and seven of them were buried on Block Island. (Block Island North Light Association)
