Phnom Penh, Cambodia. Housed in beautiful Khmer architecture, the National Museum of Cambodia is as much outdoors as inside. Birds fly freely through the exhibition spaces and land on exhibits.
Some of the ancient sculptures have been given offerings. It's a small thing, that makes the official museum feel more like a living institution than just a repository for valuable old things.
Somebody worked hard on the elaborate support structures for these dancers
And maybe all museums should have their own spirit house?
