This is the west wall of the recently-opened Shimane Museum of Ancient Izumo.
Located adjacent to Izumo Taisha, the 9,400 sq. m. building was designed by Fumihiko Waki, who chose the rusted Corten steel to express Izumo's early history of iron and steel production.
There is also lots of glass, and a shallow reflecting pool.
The grounds are extensive and include replicas of haniwa , the large clay figurines buried in association with early tombs.
With the Kitayama hills as a backdrop, the museum strikes a good balance with its immediate environment and doesn't overshadow neighboring Izumo Taisha.
