Dozens of venomous pit vipers slither and coil among the urns, roof beams and potted trees within this bizarre Chinese temple, built in 1850, and sacred to the deity Chro Soo Kong. The snakes – regarded as benevolent spirits – are seen as guardians of the temple.

For a glimpse of a uniquely Chinese form of entertainment, head to Chaoyang Theatre to watch traditional acrobatics. The one-hour show includes feats with bicycles, chairs, and other daring stunts that have been perfected over generations.

Military Museum of Colombia is run by the armed forces and aims to show you more than 200 years of the country's military history. You'll see uniforms, flags, weaponry, medals, aircraft, scaled-models of ships and some full-size vehicles. In the two courtyards you can see actual tanks, cannons and airplanes.

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.
