Wat Phra Kaew (Temple of the Emerald Buddha; full official name Wat Phra Si Rattana Satsadaram) is regarded as the most sacred Buddhist temple (wat) in Thailand. The Emerald Buddha housed in the temple is a potent religio-political symbol and the palladium (protective image) of Thai society. It is located in Phra Nakhon District, the historic centre of Bangkok, within the precincts of the Grand Palace.
The main building is the central phra ubosot,
 which houses the statue of the Emerald Buddha. According to legend, this Buddha image originated in India where the sage Nagasena prophesized that the Emerald Buddha would bring "prosperity and pre-eminence to each country in which it resides", the Emerald Buddha deified in the Wat Phra Kaew is therefore deeply revered and venerated in Thailand as the protector of the country.
