National Speed Skating Oval, Speed skating venue in Aoyuncun Subdistrict, China

The National Speed Skating Oval, known as the Ice Ribbon, is a speed skating arena on Beijing's Olympic Green. Its facade is formed by 22 ice ribbons, each 622 meters long, and the second floor has a curved curtain wall inspired by the Temple of Heaven. It covers 12,000 square meters, the largest speed skating venue in Asia, with 12,000 seats (6,800 permanent, 5,200 temporary).

Construction of the National Speed Skating Oval began in mid-2017 and was completed in 2019 on the site of the former Olympic Green Hockey Field and Olympic Green Archery Field, both used during the 2008 Summer Olympics. It is the only new venue built on Beijing's Olympic Green for the 2022 Winter Olympics, and its first competition took place on 8 October 2021.

The oval's nickname, the Ice Ribbon, comes from the 22 ribbon-like bands of its facade, each 622 metres long. The second-floor curtain wall curves in a form modelled on the Temple of Heaven. After the 2022 Winter Olympics the venue was planned for public skating and ice hockey clubs, and it is scheduled to host the 2026 Four Continents speed skating championships and the 2027 World Single Distances Championships.

The Oval stands on Beijing's Olympic Green, on the site of the former Olympic Green Hockey Field and Archery Field. It holds 12,000 spectators, of whom 6,800 seats are permanent and 5,200 temporary. After the Games it is intended as a public skating venue and for ice hockey clubs, so check which mode is operating before visiting.

The Oval is one of the few large ice arenas in the world using CO2 as refrigerant in both the cooling system and the rink pipes. Its refrigeration rack, with cooling machines, reaches 4 MW of maximum cooling capacity, and heat recovery covers ventilation, dehumidification and hot water.
