Macalester College

Macalester College was founded in 1874 and is one of very few selective liberal arts and sciences colleges located in the heart of a major metropolitan area. Macalester’s demanding academic program and commitments to internationalism, multiculturalism, and service to society are all amplified by its location in the Twin Cities of Saint Paul and Minneapolis.
