The one-kilometre-long Zaishui Art Museum in China, designed by Japanese architect Junya Ishigami, contains apertures that allow water to flow over the museum floor.
The 20,000-square-metre linear museum is situated on an artificial lake at the entrance of a new development zone in Rizhao, Shandong Province, China. It nearly fills the lake’s diameter as it runs from one side to the other.

Ishigami intended for the Zaishui Art Museum to have an under-the-lake vibe. A thin concrete roof with a gently curved shape is supported by parallel columns that rise from the lake’s bottom.
Visitors may see the lake through glass panels placed between the columns; Ishigami purposefully left spaces where the floor of the building meets the lake’s surface.
As a result, sections of the floor become submerged when water seeps into the structure. Even though the water’s surface will freeze in the winter, the water below will still be liquid and will still flow within.
