Grays Hall is a Harvard dormitory, built on the spot where Harvard’s earliest building, Old College, once stood. According to the Official guide to Harvard University of 1907:

Grays Hall, built in 1863 by the College, at a cost of nearly $40,000, is named for Francis Calley Gray, of the Class of 1809, a Fellow of the College from 1826 until 1836, John Chipman Gray, of the Class of 1811, a member of the Board of Overseers from 1847 until 1854, and William Gray, of the Class of 1829, a member of the Board of Overseers from 1866 until 1872, all three benefactors of the University.

This dorm was Harvard’s first building with water taps in the basement, freeing the residents from having to haul water in from pumps in Harvard Yard. Notable residents of Grays Hall have included: Norman Mailer, Frank Rich, Mo Rocca and Natalie Portman.
