Li Hu and Huang Wenjing are the founding partners of OPEN Architecture. Their new project, The Chapel of Sound, is an open-air concert hall nestled in a valley close to the ruins of the Ming Dynasty-era Great Wall.

Commissioned to capture the experience of music performed outdoors, the chapel’s design was informed by a search for the shape of sound. The concrete chapel has no heating or air conditioning, with a Pantheon-inspired aperture that opens to the elements. Winding staircases weave through the building to a rooftop platform that offers panoramic views of the valley and Great Wall.
