Astana is the second-largest city of Kazakhstan and is situated in central Kazakhstan and is divided east to west by the Ishim River. If you fly with Austrian Airlines to Astana, a modern pulsating city with an ancient history awaits you. Astana boasts a landscape glittering with new architecture and construction projects, due to the government spending heavily on infrastructure. However, old quarters of the city can be found on the other side of the Ishim River, inspiring the visitor to enjoy the 'traditional' Astana. The central Avenue of the Republic is the hub of entertainment and business in Astana. Sights here include the Oceanarium, the Central National Mosque, the Islamic Center, the Roman Catholic Cathedral, the Market Hall and the Bayterek Tower.
