Morningside Heights is graced with the highest concentration of institutional complexes built in a relatively short period at the turn of the 20th century, both in the city and anywhere in the United States. It is home to monumental places of worship, higher learning and healing, which accentuate its backdrop of rowhouses and apartment buildings, culminating in streetscapes that are both elegant and eye-filling. Topographically, it is situated on a plateau historically known as Harlem Heights, while geographically it is bounded by West 110th Street to the south, West 125th Street to the north, and two Frederick Law Olmsted–designed parks to the east (Morningside Park) and to the west (Riverside Park). The first institution to move into the area was New York Hospital, which began purchasing land in 1816 to establish the Bloomingdale Insane Asylum (on the present-day campus of Columbia University) and the Leake and Watts Orphan Asylum (on the present-day campus of St. John the Divine) in 1821 and 1834, respectively. The stigma of an insane asylum, compounded by inadequate transit access to the area, hindered other development until the late 19th century, when the hospital auctioned off its real estate holdings and relocated to White Plains in favor of more space and fresher air. The asylum’s relocation prompted a flurry of development by other institutions intent on expansion, starting with the Cathedral of St. John the Divine in 1887 and followed by St. Luke’s Hospital, Columbia College and Teacher’s College in 1892. The introduction of the subway into Morningside Heights in 1904, coupled with the neighborhood’s magnificent parks and prestigious institutions, led to a frenzy of speculative apartment house construction, attracting middle-class residents who could now commute directly downtown to work. Even before the advent of zoning regulations for land use, developers erected rowhouses and modest apartment buildings on the side streets and grand apartment houses on the avenues, with particularly monumental examples on Riverside Drive, Claremont Avenue and Cathedral Parkway, and mixed-use commercial buildings along Broadway, giving the neighborhood a heterogeneous yet cohesive character. Morningside Heights’ unorthodox yet distinctive sense of place comes from the coexistence of residential and institutional clusters, as exemplified by elegant rowhouses and apartment buildings just steps away from renowned academic institutions and houses of worship. Today the neighborhood still enjoys this singular sense of place. Its institutions are impressive examples of Beaux-Arts planning and design, including the graceful approach to Grant’s Tomb, the entrance façades of St. John the Divine and Riverside Church aligned with the axes of 112th Street and 122nd Street, and especially Charles McKim’s plan for Columbia University, whose symmetry and axial layout emphasize the monumentality and unity of the surrounding architecture. The residential architecture, though sometimes grand, offers a human scale and balance to the whole neighborhood.

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.

Union Theological Seminary ARCHITECT: Allen & Collins DATE: 1908-10 STYLE: English Perpendicular Gothic Rising high above the lower buildings adjacent to them, in the quadrangle of the Union Theological Seminary, the Brown Memorial Tower in the southeast corner, and the James Tower set in the middle of the Claremont Avenue side are among the finest examples of the English Perpendicular Gothic style of architecture in New York. There is a sophisticated restraint revealed in their design coupled with delicate precision in the execution of the details that seem to impart a special quality to the masonry. These striking towers are expressions in masonry of the intent of the designer and manifest the art and skill of the master stone carvers who produced them.
