Teeschlösschen

Baroque three-wing summer residence from the 1700s, modelled on Versailles.

Neoclassical city palace from 1822. Having decayed during the 1990s and 2000s, it had to be teared down and was completely rebuilt in 2014. Now it hosts the city library.

Early-Baroque palace of the Dukes of Saxe-Gotha, built in 1643–1654 as one of Germany's biggest 17th-century stately homes. The complex includes the Schlossmuseum (museum), museum of regional history, huge numismatic collection, the Ekhof-Theater (ducal court theatre), a research centre as well as the palace chapel and ducal tombs. The casemates of the palace's fortress are accessible, too.

Early Neoclassical villa built for Prince August, one of the Duke's brothers, who was a friend of Goethe and sympathised with the ideas of Enlightenment and sponsored a circle of artists, including Herder and Wieland. Since the 1990s, it stands empty.

The Dukes' arts collection, including Egyptian and Graeco-Roman antiques, Renaissance paintings, East Asian arts and sculptures of different eras.
