Wat Saket in Bangkok Old Town is an Ayutthaya-era shrine with a gleaming gold chedi in Bangkok. Also called the Golden Mount, it occupies an 80-metre-tall man made hill that was built during the reign of King Rama III. The temple welcomes worshippers year-round, though it’s busiest during its annual temple fair in November, during Loy Krathong. The temple grounds have mature trees and typical Buddhist structures such as a main prayer hall, ordination hall and library.
Wat Saket was the capital's crematorium and the dumping ground for some 60,000 plague victims in the late-18th century. At the base of the Golden Mount, you’ll find an unusual cemetery covered in vines and overgrown trees. It emits a rather spooky out-of-era vibe. Once you arrive at the top of Wat Saket, you’ll be surrounded by a wall of bells and panoramas of Bangkok Old Town.
