The campus is organized in a number of quadrangles. The Academic Quad, anchored by a statue of founder William Marsh Rice, includes Ralph Adams Cram's masterpiece, the asymmetrical Lovett Hall, the original administrative building; Fondren Library; Herzstein Hall, the original physics building and home to the largest amphitheater on campus; Sewall Hall for the social sciences and arts; Rayzor Hall for the languages; and Anderson Hall of the Architecture department. The Humanities Building, winner of several architectural awards, is immediately adjacent to the main quad. Further west lies a quad surrounded by McNair Hall of the Jones Business School, the Baker Institute, and Alice Pratt Brown Hall of the Shepherd School of Music. These two quads are surrounded by the university's main access road, a one-way loop referred to as the "inner loop". In the Engineering Quad, a trinity of sculptures by Michael Heizer, collectively entitled "45 Degrees, 90 Degrees, 180 Degrees", are flanked by Abercrombie Laboratory, the Cox Building, and the Mechanical Laboratory, housing the Electrical, Mechanical, and Earth Science/Civil Engineering departments, respectively. Duncan Hall is the latest addition to this quad, providing new offices for the Computer Science, Computational and Applied Math, Electrical and Computer Engineering, and Statistics departments.
