Commander's House served as the residence of the commander of Kastellet. It was built in 1725 in the Baroque style by architect and master builder Elias Häuser who also designed the first Christiansborg Palace which burned in 1794. Built in yellow-dressed masonry with white detailing, it consists of two storeys under a red tile roof. The triangular pediment is decorated with a relief and Christian VII's monogram under topped by a crown. It is now the official residence of the Danish Chief of Defence.
