Why you'd want to live in Mount Sinai
A beautiful North Shore hamlet on the Long Island Sound known for its history, community and beautiful homes. Mount Sinai is a hamlet located within the Town of Brookhaven in Suffolk County, New York. The population was 12,118 at the 2010 census. The hamlet is located on the North Shore of Long Island, and is served by the Mount Sinai School District and the Mount Sinai Fire Department, founded on October 25, 1930. Mount Sinai was first settled in the 1660s and was known by the name of Old Mans until a name change in the 1840s. Initially an agricultural hamlet, it transitioned into a popular resort town in the late-19th century and developed into a suburb of NY City in the mid-20th century. While primarily a residential community, the hamlet contains Mount Sinai Harbor and its popular public beach, Cedar Beach. The area was originally called Nonowatuck, or "stream that dries up", by the Seatocot family of Native Americans who lived here. The first European settlers were Colonial settlers who obtained a deed from these local Native Americans in 1664. The origin of the town's initial European name, "Old Mans", is not known. During the American Revolution, the area was under British control. However, because of its remote location the British did not have troops stationed here. Many citizens moved their families to Connecticut during British occupation. During the course of the war, American agents visited local patriots and received information, clothing, supplies and money to support the cause. In 1780, American Major Benjamin Tallmadge and a detachment of Continental Army landed at Cedar Beach and traveled south to successfully attack the British at Manor St. George. Once the Long Island Rail Road reached adjacent Port Jefferson in 1879, and temporarily continued into Mount Sinai from 1895-1939, visitors and residents began appearing from New York City. It was not until the 1960s that housing developments began to spread eastward. Lands once farmed were developed into resident areas.
