This photo of the architecture is called Wihan in Thai which is usually a large hall building in temple to keep Buddha statues and used for monk's praying ceremony in the daily basis. It is taken at an old temple names Wat lok molee in Chiangmai Thailand.
Wat Lok Moli is notable for its massive chedi, which was built in 1527-8 by King Chettharat. A viharn stands in front of the chedi. Although not particularly old, the viharn is tastefully designed.
