It was also the birthplace of traditional Thai medicine and massage.
Today is the full moon, which coincides with rituals in Theravada Buddhism, which 95% of Thais practice. The wat wasn't very busy with tourists this morning, but there were a lot of Buddhist monks and Thais coming to the temple to pray.
It was absolutely beautiful. I'm glad I'm still a bit jetlagged because 8am is the perfect time to visit a famous temple in busy, muggy, hot Bangkok. I'll let the pictures speak for themselves.
I'll end on a delicious note: my best meal yet was green curry and vegetables at a small restaurant filled with locals in Siam Square.
