Originally built for the Olympics in the Töölö district of Helsinki, the Helsinki Olympic Stadium is a masterpiece of mid 20th-century stadium architecture and the biggest stadium in Finland, mainly used for hosting big concerts and sports events. At an impressive height of 72 metres, the Stadium Tower is open for visitors and offers unparalleled views of the beautiful city. But if you want to admire the urban landscape of Helsinki from the tower or visit the Sports Museum of Finland, you will have to wait until 2020, because the stadium is currently under renovation!
