Macau Rabbit Pavilion. World Expo 2010. Shanghai
The design was inspired by rabbit lanterns popular during the Mid-autumn Festival in south China in ancient times, officials said. In Chinese mythology, the jade rabbit is a guide at the front of Nantianmen, the door leading to a fairy land.
The pavilion will be wrapped with a double-layer glass membrane and feature fluorescent screens on its outer walls. Balloons will serve as the head and tail of the “rabbit” and these can be moved up and down to attract visitors.
A spiral ramp will take visitors on a journey of Macau. A film about Macao will be screened on the roof of the pavilion.
Every visitor to the pavilion will receive a rabbit lantern.
The pavilion will be eco-friendly with recyclable construction materials as well as solar power panels and rain collection systems.
