A passerby could easily miss the new UCCA Dune Art Museum, by Li Hu and Huang Wenjing of Beijing-based OPEN Architecture. Located on a strip of sand on the Bohai Sea—not far from Beidaihe, the summer retreat of China’s Communist Party leaders—the 10,000-square-foot museum lies mostly hidden, literally buried within one of the last remaining natural dune formations on the country’s northeast coast.
