City Hall Steps Reconstruction

Constructed between 1810 and 1812, New York City Hall stands as the oldest city hall in the United States that still houses its original governmental functions. Designed by Joseph-François Mangin and John McComb Jr., the building has undergone numerous modifications by various architects over the years. The structure features a central pavilion flanked by two projecting wings, with its steps playing a significant role in civic events for over a century and a half.

The project has successfully rehabilitated the main architectural entrance stair, including the visible stair, support structure or carriage, and portico, restoring them to a safe, durable, and historically appropriate condition. This extensive restoration involved replacing the non-original exterior limestone stairs with new granite stairs and waterproofing, as well as installing a new ADA-compliant bronze handrails. Additionally, the existing temporary lift and walkway were replaced with a new permanent lift and walkway, and the automatic door opener was updated to facilitate barrier-free access to the portico. The exterior metal ramp was replaced with a new stone ramp, and the brick vault arch support was repointed and stabilized. Furthermore, the decorative paving pattern at the portico was implemented based on archival materials from the 1810 design.

As a National Historic Landmark listed on the National Register of Historic Places, New York City Hall's exterior and interior were designated as official city landmarks by the New York City Landmarks Preservation Commission in 1966 and 1976, respectively. The completion of this restoration project ensures that City Hall continues to serve as a vital and historical hub for civic activity in New York City.
