"Linnahall is a concert/sports venue in Tallinn, Estonia. It is situated on the harbour, just beyond the walls of the Old Town and was completed in 1980.

It is not to be confused with the primary administrative building of the municipal government (Raad) of Tallinn, sometimes referred to as the Town Hall).

The 22nd Summer Olympic Games were hosted in Moscow in 1980. As inland Moscow had no suitable venue at which to stage the sailing event this task fell to Tallinn, the capital of then Estonian SSR.[1] Apart from the main venue for the sailing event, Pirita Yachting Centre, a lot of other sports and entertainment facilities were built during preparations for the Olympics.[2] One of them was V. I. Lenin Palace of Culture and Sport, which was later renamed to its present name - Linnahall.[3] A large concrete structure, architect of Linnahall is Raine Karp.

The venue also features a heliport, Tallinn Linnahall Heliport, with former service to Helsinki, and a small port for Linda Line catamarans."
