Norway's 10,000-sq-metre aviation museum is huge fun to ramble around if you have a passing interest in flight and aviation history – allow at least half a day. If you're flying into µþ´Ç»åø for real, you'll see that from above, the striking modern grey and smoked-glass main museum building has the shape of an aeroplane propeller. Exhibits include a complete control tower and hands-on demonstrations. In 2016, it opened the excellent, interactive Civil Gallery on the dream of flying.
The affiliated Norwegian Air Force Museum has plenty of examples of historic military and civilian aircraft from the Tiger Moth to the U2 spy plane (the ill-fated US plane that was shot down over the Soviet Union in 1960, creating a major diplomatic incident, was en route from Peshawar in Pakistan to µþ´Ç»åø). Children and kids-at-heart will thrill and shudder at the small simulator, which, for an extra charge, takes you on some pretty harrowing virtual flights, including piloting a fighter jet.
Head south along Bankgata, then 750m eastwards along Olav V gate.
