The twisty design of the Luxembourg Pavilion is based on the Möbius strip, a unique one-sided surface with no beginning or end – just like the “circular economy” idea demonstrated inside. Known as a global banking hub, Luxembourg shows that it’s also a leader in sustainability and innovation. The pavilion experience takes the form of a “walking movie”, with exhibits ranging from Luxembourg’s cultural diversity to its prominence in fields such as satellites and space mining. And just like a great film, the best part is at the end: a 21-metre-tall slide you can coast down into a green, woody space that evokes the country’s beautiful forests.
