Construction on the royal residence of the first king of the current Chakri Dynasty began in 1762, and the complex is split into three zones: the Outer Court, where you’ll find Wat Phra Kaeo and the Emerald Buddha, Thailand’s most sacred Buddha image; the Middle Court, which contains the Dusit Maha Prasat and Chakri Maha Prasat buildings; and the Inner Court, former residence of the royal consorts. Be sure to get there early before the day is too hot.
