The famous Wat Arun perhaps better known as the Temple of the Dawn, is one of the best known landmarks and one of the most published images of Bangkok. It consists of a massive elongated prang (Khmer-style tower), and is surrounded by four smaller prangs. The prang is described by the Tourism Authority of Thailand as 104m high, while most other sources quote figures around 80-85m. It is decorated by bits of porcelain which had previously been used as ballast by boats coming to Bangkok from China, a hallmark of the reign of King Rama III. The Wat had a brief period as host of the celebrated Emerald Buddha, which now resides in nearby Wat Phra Kaew.
