Designed by German architecture firm GMP, the Baku Crystal Hall is a crystal-shaped multi-purpose indoor arena, which has been built on a peninsula near the city centre, right in the Caspian Sea. The arena has been built for Eurovision song contest 2012. It has a capacity to house a maximum of 25,000 spectators.
Built using steel, the arena comprises three independent segments including a membrane façade, the modular stadium and the interior roof. The arena is 230m long and 160m wide. The transparent membrane will offer protection from the elements of nature. More than 80,000 lamps have been incorporated into the membrane facade, which will create a dramatic lighting effect in the night.
