1 Police Plaza

One Police Plaza (often abbreviated as 1PP) is the headquarters of the New York City Police Department (NYPD). The building is located on Park Row in Civic Center, Manhattan, near New York City's City Hall and the Brooklyn Bridge. Its block borders Park Row, Pearl Street, and Police Plaza. 1PP replaced the NYPD's previous headquarters at 240 Centre Street, approximately 1 mile (1.6 km) north of 1 Police Plaza.
Description
One Police Plaza is rectangular in plan and is an inverted pyramid in elevation. It is a 13-level, horizontally-oriented brutalist building designed by Gruzen and Partners. The building was dedicated on October 16, 1973. A 22,000-square-foot (2,000 m2) expansion project was completed in 2011. Lower Manhattan residents held a rally on August 27, 2008 near One Police Plaza to protest the addition, and tenants of three neighboring co-ops filed a lawsuit to force the NYPD to undergo environmental and land use reviews.
Located on the second floor of One Police Plaza is the Real Time Crime Center, an anti-crime computer network which is essentially a large search engine and data warehouse operated by detectives to assist officers in the field with their investigations.

Why this record matters
The phrase “office building in Manhattan, New York” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Aug 1, 2026. The linked authority identifier is Q4596012. Authority coordinates are 40.712, -74.002. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1973, 2011 and 2008.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
