Miho Museum, Southeast of Kyoto, Japan, Architect: I. M. Pei
A hidden gem, this museum is built on hilly terrain, with 3/4 of the 17,400 sq ft. building carved underground into the mountaintop. The circles in the windows and tunnel give a simple beauty to the structure, while the complex roof covers the design in strips of shadow. I like the luscious trees surrounding the site and how it nestles within them. My favorite element of the structure is the bold metal bridge and tunnel that shoot into the rock face, creating a mystical entrance to a stunning realm of wonder.
