5. Wat Arun
Perhaps Thailand’s most revered Buddhist temple, The Temple of Dawn is located on the west bank of the Chao Phraya River. The temple has been in existence since Ayutthaya stood as the kingdom’s capital and held the Emerald Buddha before the Grand Palace was completed. Visitors can enter the temple after paying a modest 50 baht entrance fee. Inside, the Wat mixes 17th and 18th-century Thai architecture with ornately adorned interiors and murals.
