Chinese studio Open Architecture has completed The Chapel of Sound, a monolithic open-air concert hall in a valley next to the ruins of the Great Wall of China outside Beijing.
The project by Beijing-based practice Open Architecture is situated in a mountainous countryside area, two hours drive from the centre of the Chinese capital.
Chapel of Sound is an open-air concert hall that was built by Open Architecture
The building comprises a semi-outdoor amphitheatre, outdoor stage, viewing platforms and a rehearsal room.
Built entirely from concrete that has been enriched with an aggregate made from local stone, the concert hall has been designed to resemble a piece of the natural landscape.
It was designed to blend in with the surrounding landscape "We were very aware of the responsibility we had to contribute a thoughtful structure that fits naturally into such a unique landscape," said Open Architecture's founders Li Hu and Huang Wenjing.
"The symphony of nature is what we really wanted people to experience here."
The structure was built using concrete that was reinforced with a local stone aggregate
The rock-like structure is composed of a series of concrete layers, each of which cantilevers out from the previous layer to create an inverted cone shape.
What appears to be a solid structure is actually an inner and outer shell with the space between operating like a truss.
