Isaac Rich Hall housed BU Law until 1964. In 1964 BU Law occupied the bottom half of the current building, 765 Commonwealth Avenue on the Charles River Campus, colloquially known as the "Tower." BU Law shared the Tower with the School of Education for some years but now occupies the entire building. The School of Law's legal library, the Fineman & Pappas Law Libraries, occupies three floors in the Law Complex, spanning both the Law Tower and the Redstone Building. The Libraries also include two floors of closed stacks in the basement of the adjacent Mugar Memorial Library, BU's main library.
