Kazakhstan has unveiled a new architectural project for its capital Astana — a giant transparent tent that will contain an indoor city.
The 150m-high (500ft) dome, designed by UK architect Norman Foster, will be built in just over a year.The tent is being made from special material that absorbs sunlight to create the effect of summer inside.
Astana lies in the very heart of the Central Asian steppe. Temperatures there often drop to -30C in the winter.
