In 1860 the building was used as the barracks of the engineer battalion. In 1899 rotten wooden floors in residential premises were replaced with asphalt.

Now it is the head office of the Finnish Navy Maritime Academy, there is also a hostel for officers, training laboratories, administration and a gym.
