The first light was a wood tower and brick lantern room on top of the keeper's house.

The current tower, one of the first made of cast iron, was built in 1849.

After the opening of the Cape Cod Canal in 1914, most vessels bound from south of the Cape to the Boston area took the shorter and safer route through the canal, so there was much less traffic past the light and the light was deactivated in 1923.

It was added to the National Register of Historic Places as Monomoy Point Lighthouse on November 1, 1979, reference number 79000324.

The Lighthouse Preservation Society, the Massachusetts Audubon Society, and The Friends of Monomoy support preservation of the lighthouse and keeper's house.
