Mentioned in ancient sources as early as the 2nd century AD, the archaeological site of Ulpiana contains remnants of a Roman settlement, all clearly marked and accompanied by information boards. It was a relatively important city, whose territory covered an impressive 120 hectares, one that to-date remains largely under the radar.

This museum will take you on an electrifying trip through the history of electricity generation on the island. In the basement you can find huge diesel generators which were used in the past, and upstairs there are all sorts of electricity-related interactive exhibitions.

Burgplatz is where the little River Düssel, which gave the town its name, flows into the Rhine. In the background is the former collegiate church, St. Lambertus, with the shrine of St. Apolinaris. Next to the bridge over the Düssel, the monument to Düsseldorf being granted the privileges of a town demonstrates impressively more than 725 years of town history (town status granted in 1288). The square is dominated by Alter Schlossturm, the old palace tower (now the Schifffahrt-Museum navigation museum) and last testimony to the princely palace from the 13th century that fell victim to flames in 1872. The generously proportioned Rhine embankment promenade is considered one of the most beautiful on the Rhine. Upriver, the Medien Hafen is characterised by outstanding architectural creations, and the elegant district of Oberkassel on the opposite bank by art-nouveau facades.

A beautiful Gothic church in Ciutadella, with lovely stonework and stained glass windows, this is a peaceful and tranquil place to spend a couple of quiet hours.
