Rainier III Nautical Stadium
The Rainier III Nautical Stadium is a municipal sports complex on the Route de la Piscine in the La Condamine district of Monaco, in Port Hercules.
Built in 1961, the stadium consists of a heated saltwater Olympic-size swimming pool, with 1, 3, 5, and 10m diving platforms, and a 45m slide. The pool is converted into a 1,000m2 ice rink from December to March.
The pool gives its name to the "Swimming Pool chicane" at the annual Monaco Grand Prix. The construction of the Nautical Stadium necessitated the biggest change to the Circuit de Monaco since its creation in the 1920s.
