Wat Pho is the temple of the Reclining Buddha. Speaking of Reclining Buddhas, it's quite an iconic image in itself. There are numbers of these all over Thailand, even in other neighboring Buddhist countries. I didn't have any knowledge about the Reclining Buddha other than what it looks like but the popularity behind it made me really curious.
According to wiki
A reclining Buddha is a statue that represents Buddha lying down and is a major iconographic and statuary pattern of Buddhism. It represents the historical Buddha during his last illness, about to enter the parinirvana.
So there's that. I never had a photo when we entered the temple but it was very huge, very gold and very beautiful. You're required to take off your footwear to enter and if you'd like to make a wish or ask for good fortune, they have pennies that you can drop at the bowls along the wall on the back side of the Reclining Buddha. For a fee of course.
I preferred to walk around the temple complex. The architecture was really mindblowing. Wat Arun was beautiful but Wat Pho was something else. The prangs and chedis on the grounds were intricately designed. It is built around the same time as Wat Arun.
You can see a lot of massages being offered around the area. Apprently the temple was the first public university in Thailand, specializing in religion, science, and literature. Now it's more known as a centre for traditional massage and medicine.
