The tallest ice shell construction ever, measuring 31m high, has been built in Harbin, the capital of Heilongjiang, a province in northern China, close to Siberia.
A team led by students from the Eindhoven University of Technology worked with students from Summa College in Eindhoven and the Harbin Institute of Technology.

The tower is built of ice reinforced with paper fibres, and was formed by being sprayed on a balloon. The walls of the ice tower have an average thickness of 25cm.Â
The overall design is based on combination of traditional Chinese architecture and a flamenco dress, and is called the "Flamenco Ice Tower".

The tower took three weeks to build.
