Wat Arun (aka "Temple of Dawn") along the banks of the Chao Phraya River in Bangkok was one of my favorite temples. It is very tall, with very steep steps that you can walk up. It is extremely detailed and ornate with countless carvings and decorations embedded in the outter walls. In my limited knowledge of Asian religeous art it struck me as very Hindu/Indian influenced. This temple is a MUST SEE if you visit Bangkok.
