Kalmar konstmuseum, Art museum in Kalmar Municipality, Sweden.

Kalmar konstmuseum is a regional art museum housed since May 2008 in a four-storey, slightly irregular black cube with a wooden facade in Kalmar's city park. The winning competition entry "Plattform" by Martin Videgård Hansson and Bolle Tham adds a projecting glass volume at ground level for the main entrance.

The museum was founded in 1942 and moved to its present location in 2008, where the building received the prestigious Kasper Salin Prize for architectural excellence. This relocation represented a turning point, bringing modern design and expanded exhibition capabilities.

The museum is run by Kalmar konstförening, the art association founded in 1917, and its collection comes largely from donations by Ivar Kreuger, John Jeansson and Bessie Kreuger. It holds Swedish Romantic and modernist works, including pieces by Anders Zorn, Carl Larsson, Lotte Laserstein and Vera Nilsson, alongside art from Kalmar län and contemporary exhibitions. The association also runs the sister institution Designarkivet.

The entrance is the projecting glass section on the ground floor of the black cube in Kalmar stadspark. The building has four floors, so plan to move between levels to see the exhibitions. The museum stands on a concrete slab over medieval city and harbour layers, which were archaeologically investigated before construction.

The building rests on a cast concrete slab that sealed the medieval city and harbour layers beneath it. Where deeper structures were needed, Kalmar County Museum carried out archaeological digs, recovering finds from the early Middle Ages to the mid-1600s and revising earlier knowledge of medieval Kalmar.
