The museum is located in the suburb-city Ishøj, close to the bay of Køge (Køge bugt), 20 kilometres south of Copenhagen. ARKEN was designed by the Danish architect Søren Robert Lund, in a distinctive architectural form. It was opened on 15 March 1996 by her majesty of Denmark, Queen Margrethe.

The museum re-opened in January 2008 after major refurbishing, which included an expansion providing an additional 50% of gallery-space.
