The southern section of campus includes the Memorial Student Union, the Maynard F. Jordan Observatory, Lengyel Gymnasium and Athletic Field, the Buchanan Alumni House, as well as multiple administrative, residence, and academic halls. The recently renovated Collins Center for the Arts is also on the southern part of campus, and not only provides the Hutchins Concert Hall, a 1,435-seat venue for performing artists from around the world, but also houses the Hudson Museum, known for its contemporary Native American art, as well as displays that are culturally specific to the indigenous people of Maine. The Hilltop section of campus is populated largely with residence halls but also includes the Lyle E. Littlefield Ornamental Gardens, as well as academic and recreational facilities. The campus is also designated as an arboretum.
