Midtown campus

Columbia's campus from the 1850s to the 1890s, it was located at Madison Avenue and 49th Street and took up just one block. It has also been referred to as the Madison Avenue campus and the 49th Street campus.

The architectural style of the campus was neo-gothic, and it included both the first iteration of Hamilton Hall and the first law school building.

Once the land became too valuable and space too cramped, Seth Low moved the school to the Morningside Heights campus, where it became, for the first time, Columbia University.

It has been rumored that this campus once encompassed Rockefeller Center, but it did not, although Columbia did own the land under Rockefeller Center into the 1980s.
