The Grand Ducal Household Building in Schlossstrasse 5 was inspired by buildings of the French Renaissance and accommodated the household administration and the Office of the Major-Domo.

The Grand Ducal Government was not independent of the ruler; it had more of a supportive role. In the Government a person’s birth, education or profession could gain access to the Grand Duke. The efficiency of the authorities was greatly enhanced by the new building. This Government, the State Ministry, comprised the following departments: Foreign Affairs, Interior, Finance and Justice.

Today the Ministry of Finance uses the building.
