With the Beijing 2022 Winter Olympics due to commence on 4 February, Dezeen rounds up the most architecturally significant venues, including a new stadium by Populous and the world's first permanent structure for big air extreme snow jumping.
The majority of the venues for the upcoming Winter Games are not new, with some built as venues for the Beijing 2008 Summer Olympics as the city becomes the first ever to host both editions of the 16-day competition.
Most famous among these is the Beijing National Stadium, also known as the Bird's Nest, which was designed by Swiss architecture studio Herzog & de Meuron.
This system of reusing stadiums follows the precedent set by the Tokyo 2020 Olympic Games and has been touted by the organizing committee as a more sustainable approach. However, some notable new structures will also be on display as the Olympic cauldron is aflame once again in China.

Better known as the Bird's Nest, this Herzog & de Meuron-designed stadium is easily recognisable as the main venue for the 2008 Beijing Olympics thanks to its steel lattice envelope.
No sporting competitions will take place here next month, but the 80,000-seater stadium, for which acclaimed Chinese artist Ai Weiwei was a design consultant, will reprise its role as the host of the opening and closing ceremonies for the upcoming winter games.
