Ayuthaya
Ayuthaya is an amazing city. There are dozens of ancient wats all very close to each other. One day we rented bicycles and rode around, visiting a handful of them. It was really pleasant and quaint despite an inordinate number of roundabouts, and all the cars drove on the wrong side of the street. My bike had a bell, but it seemed rather puny compared to the elephant rambling down the road. Every wat was different, but they all had one thing in common - tons of Buddha statues.
Phra Mongkhon Bohpit.
Reclining Buddha.
At one point, they resculpted Buddha's head for a more regal look.
