Not a peg or guy rope in sight: Inside are shops, cinemas and even a beach

Designed by the British architects（建筑师） Foster & Partners, the Khan Shatyr Entertainment Centre in the capital Astana is 150m (490ft) high.

It opens on the day the city celebrates its 13th anniversary, and President Nursultan Nazarbayev his 70th birthday.

The centre has a huge indoor（室内的） leisure（空闲的，业余的） park, designed to be protected from the region's harsh climate.

Running track

Standing² on a 20m concrete base, Khan Shatyr is the city's highest structure and the world's tallest tent.

Inside, visitors will find shops, restaurants and cinemas - even an artificial beach and a running track.

Astana experiences extreme changes in temperature, from 30C in the summer to -30C in the winter.

The giant tent, which took four years to build, is designed to withstand（抵抗，禁得起） harsh weather and maintain a comfortable temperature inside.

It is the latest in an extraordinary building programme that has transformed Astana since it became the Kazakh capital 13 years ago.
