Manhasset, Nassau, Long Island

The Matinecock had a village on Manhasset Bay. These Native Americans called the area Sint Sink, meaning “place of small stones”. They made wampum from oyster shells. In 1623, the area was claimed by the Dutch West India Company and they began forcing English settlers to leave in 1640. A 1643 land purchase made it possible for English settlers to return to Cow Neck (the peninsula where present-day Port Washington, Manhasset, and surrounding villages are located.).

Manhasset Bay was previously known as Schout’s Bay (a schout being roughly the Dutch equivalent of a sheriff), Martin Garretson’s Bay (Martin Garretson was the Schout at one point), and later Cow Bay or Cow Harbor. Cow Neck was so called because it offered good grazing land. By 1659, there were over 300 cows and 5 mi (8 km) fence separating Cow Neck from the areas south of it. The settlers came to an agreement that each of them could have one cow on the neck for each section of fence the individual had constructed. The area was more formally divided among the settlers when the fence was removed in 1677. Manhasset took on the name Little Cow Neck, Port Washington was known as Upper Cow Neck.

During the American Revolution, Little Cow Neck suffered at the hands of the British. Many structures and properties, such as the 1719 Quaker Meeting House were burned, seized or damaged. The Town of North Hempstead separated from the Town of Hempstead in 1784 because the South, inhabited mainly by Church of England people, was loyal to the king. The Northern communities and villages, dominated by Yankee Congregationalists supported independence.

In 1801 it cost 2 cents to travel between Roslyn and Spinney Hill on the North Hempstead Turnpike, the newly opened toll road (now Northern Boulevard).

The Manhasset name was adopted in 1840 and comes from the native word “Manhanset”, roughly meaning “the island neighborhood.” Dairy farming was still a major endeavor but the oyster industry was also on the rise. In 1898, the Long Island Railroad arrived, bringing with it wealthy New Yorkers looking for country homes with easy transportation to more urban areas of New York City. Manhasset Valley and Spinney Hill attracted a number of skilled workers and immigrant families.

The North Hempstead Town Hall opened in Manhasset on Plandome Road in 1907. Town councilmen had previously been meeting in Roslyn taverns after North Hempstead split away from Hempstead in 1775.

The Manhasset Valley School, originally built to serve the children of the help on the local Gold Coast Estates, eventually came to serve Manhasset’s African American community, and was closed in the 1960s by a desegregation lawsuit. It is still standing and is currently used as a community center. The centrally located but antiquated Plandome Road School was demolished in the early 1970s, having been replaced by the new Shelter Rock School by 1969. Currently, Mary Jane Davies Park sits on the site of the old school.

Manhasset is served by the Nassau County Police Department, with the Sixth Precinct station house located on Community Drive, just south of Northern Boulevard. RMPs 608 and 616 are the cars assigned to patrol duties in Manhasset.

In the 2010s and 2020s, talks have been restarted to connect the businesses on Plandome Road to sanitary sewers operated by the Great Neck Water Pollution Control District. These proposals have been discussed for decades but were historically met with opposition, which killed some of the previous proposals.

Failed incorporation attempts

There have been several unsuccessful attempts over the years – especially throughout the 1940s – for some or all of the unincorporated areas of Manhasset to incorporate as villages. The most recent proposal to incorporate the hamlet took place in 2016.
