Where is columbia university?

Most of Columbia's graduate and undergraduate studies are conducted in Morningside Heights on Seth Low's late-19th century vision of a university campus where all disciplines could be taught in one location. The campus was designed along Beaux Arts principles by acclaimed architects McKim, Mead, and White and is considered one of their best works. Its original open, urban feel has been somewhat modified by the addition of such buildings as Butler Library, which have served to almost fully enclose its interior open space.
