The Amalienburg (Amalia Residence) was com­pleted by Pietro Ferrabosco in 1611. This Renaissance building, which Maximilian II built for his son Rudolf II, got its name in the first half of the 18th century when Empress Amalia, the widow of Joseph I, resided here.

The façade of the Amalienburg is crowned by an octagonal tower with an early-Baroquc helm roof. The lunar clock is said to have been designed by Tycho de Brahe, the court astronomer of Rudolf II.
