Northwestern has the Sorority Quads and the Fraternity Quads.

Sorority Quads are on the South end of Campus, and the buildings are almost all greek. Of the non-greek, half are all girls dorms (the only ones on campus).

The Fraternity Quads are on the North side of campus. The Northern quads and only 4 buildings in the quads are non-greek, one of which is the only all-male dorm.

A long time ago, someone donated a large sum of money with the stipulation that the sororities and the fraternities be on the opposite sides of campus. I assume it was to prevent "indecent behavior". That was a really long time ago (before 1900, I assume) because many houses have been up since around the turn of the century.
