Keeper James Hall, who had spent years previously at Matinicus Rock, was killed in 1916 from a rock blasting accident at Grindle Point.

The light was deactivated in 1934, and replaced with a nearby skeleton tower. The keeper’s house was converted to the Sailor’s Memorial Museum in the late 1930’s for international tourism.

In 1987 the lighthouse was relit using a solar powered optic.
