Japanese architect Kengo Kuma has unveiled his plans for the new Museum of Indigenous Knowledge in the Philippines. Located in the country’s capital, Manila, the nearly 100,000-square-foot museum will be dedicated to 4,000 years of cultural history, beginning with the Neolithic period, which inspired Kuma to design a building with a Stone Age aesthetic.

In contrast to the traditional exteriors of most cultural institutions, the Museum of Indigenous Knowledge will include an artificial ravine that carves through the center of the space, adding to the prehistoric ambience. Upon entering, visitors will be ushered past a cascading waterfall and tropical garden before descending into an underground plaza. The date for construction has not been announced.
