The Plum Island lighthouse was constructed in 1827 and rebuilt in 1869 in the same style as the Old Field and Block Island North lights. In 1997, the genrator house fell into the sea as a result of erosion and government neglect. In 2000 the USLHS began efforts to save the lighthouse and began stabilizing the eroding bluff beneath the lighthouse with rocks.
