Right in the city centre of Jülich sits the Citadel, one of the best preserved fortresses in Germany and a prime example of Italian High Renaissance architecture north of the Alps. Built in the 16th century as part of an ideal city concept under the reign of Duke William V., it survived numerous wars and sieges. Today it houses the Museum Zitadelle Jülich with its exhibition depicting 2000 years of Jülich’s history and containing one of the most impressive collections of works from Jülich’s most famous son, 19th century landscaper Johann Wilhelm Schirmer.

The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
