During the early 1800s Bass River was an important safe harbor for schooners and fishing ships in Nantucket Sound. At that time, a small light was placed in the upper window of a private home to help mariners in the area. In 1850, the
federal government of the United States appropriated $4000 to build a lighthouse near the breakwater at the mouth of
Bass River. In 1854, construction began on the light and keepers home. As was typical of early
Cape Cod style lighthouses, the light tower was an integral part of the keepers house, centered atop the dwelling's roof. Because most of these structures leaked significantly, they were replaced with self-standing towers; the West Dennis Light is the only remaining lighthouse on Cape Cod built with this design. The light was lit in 1855, and continued in service until 1880, when the
Lighthouse Service decided the Bass River Light was no longer necessary since a new light had been built at Stage Harbor in
Chatham. After many complaints, the light was relit a year later. ==Deactivation and hotel use==
