Albertus Magnus College is a small private liberal arts college in New Haven, Connecticut, United States. It is located about two miles (3 km) from the central campus of Yale University in a residential area near the border with Hamden. The neighborhood is on Prospect Street just above Edgerton park and near East Rock. The college uses several of the area's historic 19th-century mansions as classroom and administrative buildings. Since 1926, the College has acquired several mansions, which are now used for student housing and administration. Rosary Hall has become the College library. The latest new construction on campus is the Academic Center for Science, Art and Technology, which opened for classes in January 2005 and designed by Barry Svigals. Albertus Magnus College became co-educational in all its programs in 1985. In the same year, the Continuing Education Division expanded its offerings for the adult learner to include a pioneering Accelerated Degree Program. In 1994, the College introduced New Dimensions, an alternative educational delivery system focused on business, also for the adult learner. This program now includes undergraduate and graduate courses.
