Pershing Square Building ARCHITECT: York and Sawyer, John Sloan DATE: 1921-23 STYLE: Lombard Revival The Lombard Revival-style Pershing Square Building anchors a prominent corner directly across 42nd Street from Grand Central Terminal at Park Avenue. Designed by John Sloan, working with staff of York & Sawyer, the building is remarkable for the important role it played in the development of the city’s mass transit system, its transitional role in the history of the city’s building development, and its exceptional terra-cotta cladding. The Pershing Square Building is also noteworthy as an integral element of the redevelopment of the Grand Central Terminal area.

In the closing decades of the 19th century, New York underwent a profound physical and cultural transformation. Fueled by the wealth of the exploding financial and manufacturing sectors, the city rapidly evolved into a world-class metropolis. The bold ambitions of civic and business leaders, architects, and engineers of the era manifested in landmarks such as the vast Cathedral of St. John the Divine, the stately U.S. Custom House, the towering Municipal Building, and the original terminus of New York City’s first official subway line—the ornate City Hall stop. The sweeping interior spaces common to all of these structures, and hundreds of others, depended upon a venerable Mediterranean building technology adapted to contemporary American construction: arched tile ceilings—or vaults—that were not only self-supporting but could also bear the weight of floors or roofs above them. These vaults were designed and built by a single New York firm, founded by Spanish immigrant Rafael Guastavino (1842-1908) and later headed by his son Rafael Jr. (1872-1950). The Guastavinos’ patented system for building domes and vaults involved multiple layers of thin ceramic tiles bonded with quick-drying mortar. The resulting structures were not only exceptionally strong, but also lightweight, easy to build, and inherently beautiful, thanks to intricate patterns of exposed tile that formed finished, decorative surfaces. Guastavino vaults figured prominently in more than 1,000 projects across the nation, including 200 in Manhattan alone. During its 73-year history, the Guastavino Company helped build some of the most impressive interior spaces in America—veritable palaces for the people. This list based on MCNY's exhibition Palaces for the People, contains many of Guastavino's masterpieces in the five boroughs, both those that remain and those that have been lost to the wrecking ball.

William Wilgus, New York Central Railroad's largely self-taught chief engineer, was the mastermind behind Grand Central Terminal's innovative engineering technology. With the plan for electrification and the sinking of the railroad tracks below grade, while building the new modern terminal, Wilgus also convinced railroad officials to commercialize the air above the new street-level decking. In leasing the area above the tracks to developers, the Railroad could increase its profits and create a bustling business district that surrounded, supported, and benefited from Grand Central Terminal. Terminal City, as it was called, began to develop even before GCT was complete in 1913. Between 1909 when the Grand Central Post Office opened and the early 1930s when the Depression largely halted construction, the neighborhood boomed with hotels, apartment hotels, private clubs, and office buildings. Many of these structures were designed by Warren & Wetmore, one of the two architectural firms that created Grand Central. Most of the best-known hotels of Terminal City, including the Biltmore, Roosevelt, and the Commodore, were constructed by the mid 1910s, while the office buildings, including the Graybar and New York Central Buildings, were largely completed in the 1920s. This walk does not propose to be a complete list of all Terminal City development. It does not include any post-World War II constructions and it concerns itself ONLY with some of the Terminal City structures that are still extant. Some of the buildings will be easily recognizable, while others, though technically the same structure, bear no resemblance to their former selves. So lace up some comfortable shoes and let's get exploring.

Pershing Square Building, 1940. In 1914 the hotel which had previously occupied this large corner lot, the Grand Union Hotel, closed after it was acquired by the city. The city and its transit agency, the Interborough Rapid Transit Company, had big plans for the site. They proposed a large diagonal subway station which would connect the older section of the IRT (under Park, then Fourth Avenue) and the new section (which would proceed uptown via Lexington Avenue). The building was razed and despite wartime delays the station was complete in 1920, providing a strong foundation for the construction of a large building above. Designed by John Sloan, working with the architecture firm of York & Sawyer, the 1923 Pershing Square Building is a Lombard Romanesque- Renaissance Revival structure. The textured brickwork and multi-colored terra cotta of the facade predates its popularity in later Art Deco buildings. Interestingly, because the subway station foundations of the building were begun prior to the 1916 zoning laws, it was was designed without adherence to newly required regulations regarding setbacks (it was the last tall building without setbacks). Given its prime location above the busy subway station and adjacent to the railroad station, the building was a very successful venture within Terminal City. Early tenants included a number of large corporations, such as the Irving Trust Company, as well as smaller offices of real estate agents, lawyers, and investors. The building was renamed the American Can Building in 1945 for one of its then largest tenants. Today called the Pershing Square Building, once again, or simply 125 Park Avenue, the Terminal City office building remains largely unchanged and was designated a landmark in 2016.
