Pirate lore surrounds this black and white marker which has guided boat traffic for a century.
Material was quarried from the island to be used as ballast for ships during the 1600s and slate was quarried in the 1700s. In 1636, it was granted to John Gallop, a harbor pilot who resided on Gallops Island and grazed his sheep on the then 12-acre "Nixes Island." Corpse of an executed criminal, pirate William Fly, was chained and two other pirates buried on the island, then (1726) called "Nick’s Mate." Pyramid beacon perched on granite base which was erected by Boston Marine Society, 1805. Date of current wooden pyramid is unknown. (Further research is currently being conducted.)
