117th Street
117th Street does not exist. At least, not in Morningside Heights. The stretch of the street that once lay betweeen Riverside Drive and Morningside Drive was first eviscerated by the main Columbia campus, which when constituted as a superblock in the 1890s stretched from 116th Street to 120th Street. The next segment to go was that between Broadway and Claremont Avenue, swallowed for the Barnard campus.
The remaining portion of the street, between Amsterdam Avenue and Morningside, was actually developed with rowhouses, which contained the original homes of many Columbia and other organizations, including:
- At 435, the "Casa de las Espanas," as Casa Hispanica was then called (now with its own dedicated building on the other side of campus)
- At 429, the Frankfurt School's Institute for Social Research
- At 423, the original Deutsches Haus (now in King's Crown
- At 419, the Geological Society of America
- At 415, the office of the Dean of Columbia College (now in Hamilton Hall)
- At 413, the office of the University Chaplain
- At 411, Maison Francaise (now in Buell Hall)
- At 405, the Carnegie Endowment for International Peace, since University President Nicholas Murray Butler was in charge of it
But these were all torn down, and the street abandoned, when the elevated plaza that leads to East Campus and the International Affairs Building was constructed in the 1960s and 70s.
A vestigial street sign announcing the presence of 117th Street still stands on the eastern side of Morningside Drive where it once intersected with the street. It now points to the ugly metal gate between Faculty House and East Campus.
