At 120th is the Teachers College, founded in 1886 by Miss Grace Dodge. This also is now a part of Columbia. One of the most notable structures along the ridge is that of St. Luke's Hospital, opposite the Cathedral grounds, at 113th Street. Back from the river and hidden, except at one or two points, where a transverse \^alley crosses the main ridge of the island at i6ist Street, stands the historic Jumel mansion, as it is usually called.

Immediately above Riverside Park is the former village known to its residents as Manhattanville. A steel viaduct spans the Manhattan Valley and connects Riverside Drive with the Harlem Speedway.
