Wat Phra Kaew (English: 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 temple complex is located in the Phra Nakhon District of Bangkok.

The Grand Palace is a complex of buildings at the heart of Bangkok, Thailand. The palace has been the official residence of the Kings of Siam (and later Thailand) since 1782. The king, his court and his royal government were based on the grounds of the palace until 1925. King Bhumibol Adulyadej (Rama IX), resided at Chitralada Royal Villa in the Dusit Palace, but the Grand Palace is still used for official events.

Rather than being a single structure, the Grand Palace is made up of numerous buildings, halls, pavilions set around open lawns, gardens and courtyards. Its asymmetry and eclectic styles are due to its organic development, with additions and rebuilding being made by successive reigning kings over 200 years of history. It is divided into several quarters: the Temple of the Emerald Buddha; the Outer Court, with many public buildings; the Middle Court, including the Phra Maha Monthien Buildings, the Phra Maha Prasat Buildings and the Chakri Maha Prasat Buildings; the Inner Court and the Siwalai Gardens quarter.
