Lonely Planet review
Striking Wat Arun commands a martial pose as the third point in the holy trinity (along with Wat Phra Kaew and Wat Pho) of Bangkok's early history. After the fall of Ayuthaya, King Taksin ceremoniously clinched control here on the site of a local shrine (formerly known as Wat Jaeng) and established a royal palace and a temple to house the Emerald Buddha. The temple was renamed after the Indian god of dawn (Aruna) and in honour of the literal and symbolic founding of a new Ayuthaya.
It wasn't until the capital and the Emerald Buddha were moved to Bangkok that Wat Arun received its most prominent characteristic: the 82m-high Ъrahng (Khmer-style tower). The tower's construction was started during the first half of the 19th century by Rama II and later completed by Rama III. Not apparent from a distance are the ornate floral mosaics made from broken, multihued Chinese porcelain, a common temple ornamentation in the early Ratanakosin period, when Chinese ships calling at the port of Bangkok discarded tonnes of old porcelain as ballast. At press time, it had been announced that the Ъrahng would be closed for as long as three years due to renovation. Visitors can enter the compound, but cannot, as in previous years, climb the tower.
Also worth an inspection is the interior of the bòht . The main Buddha image is said to have been designed by Rama II himself. The murals date from the reign of Rama V; particularly impressive is one that depicts Prince Siddhartha encountering examples of birth, old age, sickness and death outside his palace walls, an experience that led him to abandon the worldly life. The ashes of Rama II are interred in the base of the presiding Buddha image.
Frequent cross-river ferries (3B, from 6am to 8pm) run over to Wat Arun from Tha Tien.
Sunset views of the temple compound can be caught from across the river at the riverfront warehouses that line Th Maha Rat. Another great viewpoint is from Amorosa, the rooftop bar at the Arun Residence.
