After the war, Tartu was declared a "closed town" to foreigners, as an airbase for bombers was constructed on Raadi Airfield, in the northeast outskirts of the city. It was one of the biggest military airbases in Eastern Europe and housed strategic bombers, that carried nuclear bombs. The location itself was where the Estonian 2nd Air Division was situated prior to the Soviet occupation. The concrete runway there now houses a large used cars market and is sometimes used for automotive racing. On one end of an older strip of the runway, the new building of Estonian National Museum was built.
