Amsterdam Beach State Park
State park in Suffolk County, New York
Amsterdam Beach State Park is a 199-acre (81 ha) undeveloped state park on the Atlantic Ocean in the Town of East Hampton just east of Montauk, New York. The land is also known as the Amsterdam Beach Preserve.
History
The area is referred to locally as the Montauk Moorlands, and was privately owned prior to the state's initial purchase of 122 acres (49 ha) in 2005. The land was acquired for a total of $16.5 million, of which the Town of East Hampton paid $6 million, Suffolk County paid $5.5 million, New York State paid $4 million, and $1 million was paid from a federal grant.
At the time of its purchase, the property represented one of the largest unprotected continuous tracts of undeveloped land in Montauk. An additional 77 acres (31 ha) of adjacent property was acquired in 2008, increasing the park's size to nearly 200 acres (80.9 ha).
The property is owned jointly by New York State, the Town of East Hampton and Suffolk County.
Park description
The park, located between Shadmoor State Park and the Nature Conservancy's Andy Warhol Preserve, is largely undeveloped and is maintained with the intention of preserving its value as natural habitat. It includes 1,288 feet (393 m) of ocean frontage, several ponds and 54 acres (22 ha) of tidal and freshwater wetlands.
Woody vegetation at Amsterdam Beach consists mainly of shadbush (Amelanchier), highbush blueberry (Vaccinium corymbosum), black cherry (Prunus serotina), arrowwood (Viburnum dentatum), and several species of holly (Ilex).
This brief starts where responsible research should: with the source description of “Amsterdam Beach State Park” as state park in Suffolk County, New York. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as state park in Suffolk County, New York. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Aug 18, 2026. The linked authority identifier is Q4748825. Authority coordinates are 41.044, -71.897. 1 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2005 and 2008.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
