The Tyumen Region is the only region in Russia to share a border with both the Arctic Ocean and with Kazakhstan. It also borders with the Arkhangelsk, Omsk and Tomsk Regions, the Republic of Komi and the Krasnoyarsk Territory. It is sometimes referred to as the Gateway to Siberia, and a great deal of the regions experiences extreme natural and climatic conditions.
The administrative centre is the city of Tyumen which is one of the oil capitals of Russia. One of the most colourful and mysterious characters in Russian history was born in this region - the mad monk Grigori Rasputin - a favourite of the last tsar and tsarina. A popular destination in the region for tourists is the city of Tobolsk which boasts the only kremlin found in Siberia. Many participants of the failed Decembrist Rebellion of 1825 were subsequently exiled to the Tyumen Region.
