Wat Pho

This is the temple of the Gigantic Reclinging Buddha- and they do mean gigantic. It's the full length of this temple and it probably stands a good 20+ feet high and he's laying on his side, so the length is easily 100+feet I would think. The entire thing is coverred in gold and the bottom of his feet are covered in intricate mother of pearl work. The gruonds are quite beautiful as well and have several different buildings. There is also a well known school located on the premises that is famous for thai massage as well.
