Arts and culture
In 2004, the U.S. federal government placed Spencer's downtown business district on the National Register of Historic Places. Also in 2004, the State Historical Society of Iowa certified the Spencer Downtown Cultural District  as one of the initial eight such projects across the state. Spencer's proposal for this designation included remodeling the old Spencer Middle School building into a multi-purpose facility with a senior citizen center, affordable housing units, and a restored facade. Future work on the old Middle School project involves restoration of the historic auditorium. Also part of the State Historical Society designation is the city's renovation of its Grand Avenue bridge to include commissioned stained glass plates in an Art Deco style.
Current cultural attractions in Spencer include the Spencer Community Theater, the Parker Historical Museum, public art displays, and the Bogenrief Glass Studio. Arts on Grand  is a nonprofit organization supporting local area artists with a gallery shop, exhibits, classes, workshops, tours, fundraising events, and other activities. The Curiel-Reynolds School of Visual Arts (CRVA)  relocated from Detroit to Spencer in 2007.
