Travel back to ancient times at this renovated Roman-age villa, discovered only recently in the 19th century. It houses an archaeological museum, and has well-tended rose and herb gardens. Special programmes like donkey tours and overnight stays can be organised here too.

Saarbrücken has plenty to offer to the lovers of architecture, and one unmissable landmark is the city's town hall, built at the turn of the 20th century in neo-Gothic style and designed by Georg Von Hauberrisser, whose works also include the town hall in Munich.

The museum's treasures date back 3000 years including historical relics from the Sun and Immortal Bird gold decoration to gold mask and jade accessories. Exhibition in Jinsha awarded the Chinese Top Ten Excellent Exhibition, and you can experience the brilliance of Chengdu's history and splendour of the ancient kingdom here.

In addition to the Rotonda, this is one of the two most characteristic monuments in town. The Galerius arch is situated close to the eastern city wall, a short distance from the Kassandreotiki gate. The 4th-century AD Roman emperor Galerius commissioned both structures to show off his power. A road used to run through the arch, past the Rotunda and on to the palace to the southwest. The arch is composed of a masonry core faced with marble sculptural panels celebrating a victory over the seventh emperor in the Sassanid Persian Empire. About two-thirds of the arch is preserved. Colloquially, the monument in known as Kamara, that's Greek for 'arch'.
