The red-brick building was completed in 1905 based on Martin Nyrop's design, who was inspired by medieval Danish architecture and the Renaissance style of northern Italy. A room on the ground floor is given over to the astronomical clock, by Jens Olsen (1872-1945), which gives the sidereal time as well as solar time everywhere in the world. It indicates the trajectory of the planets around the sun and calculates the eclipses of the sun and moon with great accuracy: within half a second every 300 years! Pretty view from the top of the tower.
