Given beauty of the architecture and the fine craftsmanship it is not surprising that Wat Arun is considered by many as one of the most beautiful temples in Thailand. The spire (prang) on the bank of Chao Phraya River is one of Bangkok's world-famous landmarks. It has an imposing spire over 70 metres high, beautifully decorated with tiny pieces of coloured glass and Chinese porcelain placed delicately into intricate patterns.
