Rakhang Khositaram Temple, formerly known as Wat Bang Wa Yai, is an ancient monastery dating back to the Ayutthaya period. Its prominence grew during the early Rattanakosin era when a large ancient bell with a remarkably resonant tone was discovered within the temple grounds.

King Phutthayotfa Chulalok (Rama I) ordered the bell to be relocated to the Temple of the Emerald Buddha and graciously presented five new bells to the temple. He also renamed it “Rakhang Khositaram Temple,” meaning The Monastery of the Resonant Bell.

The temple became nationally renowned as the residence of Somdet Phra Phutthachan To Phrommarangsi (Somdet To), one of Thailand’s most revered monks. Devotees from across the country visit to pay homage and chant the Chinabanchorn mantra, believed to bring protection and spiritual strength.

Inside the ordination hall enshrines the principal Buddha image known as the “Smiling Buddha Receiving the Sky,” a bronze meditation Buddha admired for its serene expression and compassionate presence. The surrounding murals depict scenes from the Buddha’s life and Thai classical literature, reflecting the devotion and artistic excellence of early Bangkok craftsmen.

Another highlight is the Tripitaka Library (Ho Trai)—three wooden buildings standing above a pond to protect sacred scriptures from moisture and insects. Decorated with gold lacquer designs and intricate carvings, the library houses murals painted by Ajarn Nak, illustrating daily life and attire of early Rattanakosin society.

Situated along the Chao Phraya River in Bangkok Noi district, the temple offers peaceful riverside scenery. Visitors often arrive by boat, experiencing the traditional waterfront lifestyle of Bangkok. The gentle sound of temple bells and the flowing river create a deeply calming atmosphere.

Rakhang Khositaram Temple is therefore not only a sacred religious site but also a cultural treasure and a serene spiritual retreat in the heart of bustling Bangkok.
