Defence Command is co-located with the Ministry of Defence in the Kaartinkaupunki neighborhood of Helsinki at the Guard's Garrison, designed by architect Carl Ludvig Engel and completed in 1822. The building served as the original garrison of the Guard of Finland and from 1918 to 1938 as the garrison of the White Guard. It was destroyed during the Continuation War in the February 1944 bombing of Helsinki and rebuilt after the wars as well as supplemented in the 1960s with additional buildings designed by architects Viljo Revell and Heikki Castrén.
