Asian Historical Architecture
I just discovered the web page Asian Historical Architecture: A Photographic Survey and - WOW! - it's amazing. The pleasantly simple interface lists the various countries (nineteen) and buildings (a lot) on the left, with the images and other information displayed on the right. While the images aren't huge, the coverage is impressive and some helpful maps are used with some buildings to orient the viewer, like Japan's Himeji Castle (below). Most importantly, the images are quite beautiful.
