Dahl Centennial Union

Dahl Centennial Union was originally built in 1960-61 during the observance of the 100th anniversary of the college's founding, with additions to the second and third floors in 1973, and a $6.5 million renovation and addition in 2006. The Union is built on a bluff overlooking the Oneota Valley and the Upper Iowa River and features an entryway with a 30-foot glass-enclosed atrium.

A hub for campus life, the Union contains the major dining halls; Marty's (a cyber-café); Oneota Market (a food pavilion connected to a student lounge with open seating, a fireplace, a solarium overlooking the Oneota Valley, and computer workstations); a centralized mail center; a large new book shop; the diversity center; the student-run radio station (KWLC); lounges; conference rooms; the college president's and vice-presidents' offices; offices for student services, student government, student organizations, and student publications; career development offices; public information offices; student life and admissions offices; an art gallery; and banquet and community dining facilities.

Rededicated as the "Bert M. and Mildred O. Dahl Centennial Union" in October 2006, the facility commemorates the Dahls, friends of the college, whose gift helped make the 2006 renovation possible.
