This is its official title; sometimes the theatre is nicknamed The Siberian Coliseum. 

Completed during the Second World War, and with its first performance three days after peace in Europe on 12 May 1945, it is arguably the most extraordinary building in all Siberia. 

Located on Lenin Square, it includes a vast dome some 60 metres wide and 35 metres high supported by neither columns nor girders.

The dome is some 8cm thick, meaning that the ratio to its radius is less than that of a hen's egg. 

The theatre has a capacity of just under 1,800, with a total area of 11,837 square metres and a volume of 294,340 cubic metres. If its vital statistics are awesome, so too are its ticket prices, with opera from 130 to 1,000 roubles (€24, $30) and ballet from 200 to 2,500 roubles (€61, $77).
