At the suggestion of public association “Colonel Kalpaks’s Battalion”, in the summer of 1935, construction works began to erect Colonel Oskars Kalpaks Museum opposite his memorial site in “Airītes”. The museum was unveiled on 6 September 1936. The building housed an exhibition about the fighting days of Kalpaks’s Battalion. During Soviet occupation, the memorial ensemble was destroyed, only to be restored come 1989. On 11 November 1990, Colonel Oskars Kalpaks Museum resumed its operation. From 1991 to 2006, the memorial site was a branch of the Janis Rozentāls History and Art Museum of Saldus. Since 2 January 2007, it functions under the auspices of the Latvian War Museum. On 6 March 2013, the museum revealed its brand new exhibition display, which illuminates the persona of Colonel Oskars Kalpaks and highlights his role in World War I and Latvia’s Liberation Battles.
