Founded in 1986 by Professor John Beetlestone and his colleagues from Cardiff University, Techniquest is a discovery and science centre with many exhibits and activities for children and science lovers. Inside you will find a science theatre, a planetarium and more than 120 different exhibits where you can test your abilities and discover more about the world of science and technology.

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.

Dortmund’s TV tower, 212 metres high, and located in Westfalenpark. At one point in time, it was the tallest building of Dortmund. The views will show you the impressive views of the Westfalen Park and the city itself. Take the lift up towards the sky, eat and have a drink in the revolving restaurant and stroll around the 70-hectare park.

Undoubtedly one of the world’s top tourism destinations — and officially one of the New Seven Wonders of the World — the Great Wall stretches for thousands of kilometres across northern China. From Beijing, the easiest section to reach is Badaling, about 70 km from the city. It’s well restored and has a cable car, but it also draws the biggest crowds. Mutianyu is another popular choice with fewer tour groups if you go early. For a wilder feel, head to Simatai or Jinshanling, where much of the wall is original and the hikes are longer. Huanghuacheng is partly submerged by a reservoir, so you get the unusual sight of watchtowers half surrounded by water.
