The Ordos Museum in Inner Mongolia is like a huge time cave that has landed on the sand dunes. Its interior is full of natural light, transforming the city ruins into a poetic public cultural space. The internal streamline is a continuous line that swims in the light and shadow, sometimes dark and private, sometimes bright and spectacular. The bridge in the canyon connects the exhibition halls on both sides, and people will repeatedly meet on the bridge passing through the air during the tour. The exterior wall of the museum uses a large area of solid wall and aluminum veneer curtain wall to withstand the severe cold and bad weather in Ordos.
