345 Park Avenue
The year 1969 marked the completion of a 44-floor skyscraper in Midtown Manhattan. Emery Roth & Sons designed the structure to occupy an entire city block between Park Avenue and Lexington Avenue. Developer Samuel Rudin secured a zoning bonus by including open space under the city's 1961 Zoning Resolution. This public plaza spans the full blockfront on Park Avenue and extends back along part of the 51st Street frontage. The plaza sits on the west side of the site to align with adjacent open spaces at the Seagram Building and St. Bartholomew's Church. A sculpture named Dinoceras by Robert Cook stands within this open area. Jack and Lewis Rudin commissioned the piece, which was dedicated in 1971.
This building occupies land that once held the Hotel Ambassador, which opened its doors in 1921. Several townhouses and tenement buildings also stood on this same block before construction began. Sheraton Hotels purchased the hotel in 1958 and renamed it the Sheraton-East. Demolition crews tore down the former hotel in 1966 to make way for the new tower. The project replaced these older structures with a modern office complex. In 2024, owner Rudin Management announced plans to build a fitness center and restaurants for workers inside the building.
The structure received its own assigned ZIP Code 10154 during its early years of operation. This designation makes it one of only 41 buildings in Manhattan with such a unique postal assignment. Most other skyscrapers share codes with surrounding blocks or neighborhoods. The building sits near the Racquet and Tennis Club and Park Avenue Plaza to the northeast. It is close to the Seagram Building to the north and 599 Lexington Avenue to the northeast. St. Bartholomew's Episcopal Church and the General Electric Building lie to the south.
Television viewers saw the exterior of 345 Park Avenue used as a filming location between 1998 and 2000. Aaron Sorkin created the series Sports Night which featured the building as headquarters for fictional companies CSC and Continental Corp. The show ran for two seasons using the real-world architecture as a backdrop. No interior scenes were filmed on-site according to available records. The exterior shots helped establish the corporate setting for the drama.
Key corporate occupants include The Blackstone Group, KPMG, and the National Football League since 2012. Other tenants listed are Capital Trust, Loeb & Loeb LLP, ClothesFlow.Co, Wafra Inc., and The Rudin Management Company, Inc. The NFL moved its offices into the tower in 2012. This tenant mix reflects the building's status as a major commercial property in Midtown Manhattan. The presence of multiple large firms indicates high occupancy rates over recent decades.
On the 28th of July 2025, four people died and another was injured during a mass shooting inside the building. A 27-year-old man named Shane Tamura shot victims with an AR-style rifle in both the lobby and on the 33rd floor. Tamura later took his own life after the attack. The incident occurred within the office floors and public areas of the skyscraper. Police investigated the crime scene following the event.
