The University's main Charles River Campus follows Commonwealth Avenue and the Green Line , beginning near Kenmore Square and continuing for over a mile and a half to its end near the border of Boston's Allston neighborhood. The Boston University Bridge over the Charles River into Cambridge represents the dividing line between Main Campus, where most schools and classroom buildings are concentrated, and West Campus , home to several athletic facilities and playing fields, the large West Campus dorm, and the new John Hancock Student Village complex.
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.
