United States Post Office (Pearl River, New York)
government building in Pearl River, New York, United States
The U.S. Post Office in Pearl River, New York, is located at the junction of Franklin Avenue and South Main Street in the hamlet's downtown. It is a brick building from the mid-1930s, serving the ZIP Code 10965, which covers the hamlet of Pearl River.
Its design, an application of the Colonial Revival architectural style commonly used for post offices of that era, is unique to it. It shows a strong modernist influence, with almost no ornament on its exterior, and no public art inside.
In 1988 it was listed on the National Register of Historic Places with many other contemporary post offices in the state, including four others in Rockland County. Congress renamed the building the Heinz Ahlmeyer, Jr. Post Office Building in 2005, in honor of a local soldier missing in action and presumed dead during the Vietnam War until that year, when his remains were identified.
Building
The post office is located on the west side of Main Street, just south of its junction with Franklin Avenue on the east. It is oriented east-west, with its north (front) elevation facing the parking lot for the train station to its northwest. Across the parking lot to the north is Pearl River's town square; commercial buildings line its east side.
This brief starts where responsible research should: with the source description of “United States Post Office (Pearl River, New York)” as government building in Pearl River, New York, United States. 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 government building in Pearl River, New York, United States. 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 Sep 6, 2026. The linked authority identifier is Q7891026. Authority coordinates are 41.058, -74.022. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1988 and 2005.
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.
