About Mount Sinai

Situated in the town of Brookhaven on the north coast of Long Island, Mount Sinai is a fairly small hamlet in Suffolk County, New York. It's home to one of the area's most popular public beaches, Cedar Beach, as well as Mount Sinai Harbor. Largely an agricultural and shipbuilding area in its early years, Mount Sinai retains much of this original charm.

The History of Mount Sinai

As is true for most communities in this area, Mount Sinai's first residents belonged to the Setauket and Unkechaug tribes. English settlers purchased the land around Mount Sinai in 1655, and more purchases a few years later led to quick development throughout Long Island.

Up until the late 19th century, development in Mount Sinai occurred mostly in short bursts, generally within a 2-mile radius of the harbor. There were some homes and several farms in the area, and in 1840, the community applied for a post office. The town was called Old Mans at the time, which the government deemed unacceptable. It was temporarily named Mount Vernon, but it was changed to Mount Sinai when locals realized there was already a town called Mount Vernon in New York. A thriving shipbuilding industry was born, due largely to the numerous trees throughout the area. This helped fuel population growth, but commercial development lagged far behind.

Through the late 19th and early 20th centuries, Mount Sinai was a popular resort town and vacation destination. Growth increased to keep up with the influx of new visitors, which included famous people including Marilyn Monroe. The community turned quiet once again as development slowed, and it remained that way for some time. However, the 1960s brought suburbanization, which led to the construction of a number of housing developments. Today, several private communities have replaced the farmland that was a part of Mount Sinai for so long.
