Sea Gate is a private, gated community at the far western end of Coney Island at the southern tip of the New York City borough of Brooklyn. It contains mostly single family homes, some directly on Gravesend Bay. It is regularly patrolled by the Sea Gate Police Department which was established in 1899, though the New York City Police Department has joint jurisdiction over it.
The chapel, once used for services and built in 1901, is a historical building now used for social events, and is a polling site at election times. The Chapel with its stained-glass windows is the first structure seen when entering the main (police protected) gate.
In addition to the large and private beach areas, Sea Gate has two parks:
A playground with a basketball court, skateboard ramps and children's jungle gym pieces is located next to the Sea Gate Community Center on Surf Avenue. The community center is across from the Sea Gate Beach Club which offers entertainment, dining, one of Sea Gate's private beaches, and two swimming pools.
Lindbergh Park near the Coney Island Light at Norton's Point is a sandy/grassy patch of land with stunning views of Lower New York Harbor and the Verrazano-Narrows Bridge. "Lindy Park," as it is known to residents, has a children's playground, spectacular panoramic ocean/bay views, and space for sitting, picnicing, kite flying, baseball playing, or just enjoying the ocean.
The beaches in Sea Gate are uncrowded and patrolled during the summer by lifeguards. The beach is private and visitors must show beach passes.
As of 2000, Sea Gate has a population of 49,343 with a total of 18,413 households.
