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." In the early 1700s, the body of an executed criminal, pirate William Fly, was chained to the island, and two other pirates were buried here. At the time, the island was called "Nick’s Mate" (1726). The Boston Marine Society erected the pyramid beacon perched on granite base in 1805. Date of current wooden pyramid is unknown. (Further research is currently being conducted.)
