This is a 'wat' (theravada Buddhist temple) in Thailand, actually a complex of some 20 buildings including the main temple and restrooms for tourists, housing for resident monks etc, all made primarily out of empty bottles. (The temple apparently has a concrete structural core.)
The monks started picking up empty bottles on their rounds in 1984, and tried to think of ways to reuse them so as to keep them out of landfills. They hit on using them as a building material and set to work. The local government's garbage collectors started giving the monks the bottles they collected as well, and it took off. Since this building material is inexhaustible, the construction is ongoing. The temple contains mosaics made out of recycled bottle caps.
