Wat Ong Teu Mahawihan

Overview

Wat Ong Teu Mahawihan is one of the most important Buddhist monasteries in Laos, serving as the centre of Lao Buddhist scholarship and home to the Buddhist Institute. Its name means "Temple of the Heavy Buddha" — a reference to the large 16th-century bronze Buddha image in the sim.

Highlights

• Heavy Bronze Buddha: The massive seated bronze Buddha reportedly weighs several tonnes and dates to the Lan Xang era.
• Buddhist Institute Library: The monastery houses one of the most important Buddhist study centres in Laos, where monks pursue advanced Pali and Dhamma studies.
• Elaborate Sim Architecture: The ordination hall features an impressive multi-tiered roof and gold-leaf interior murals.

History

The temple was established in the 16th century during the reign of King Setthathirath. Destroyed in the 1828 Siamese invasion, it was rebuilt in the 19th and 20th centuries and expanded as an educational centre for Theravada Buddhism in Laos.

Visitor Tips

• Tip 1: The temple sits between Wat In Paeng and Wat Mixai — consider visiting all three on a walking route through the old town.
• Tip 2: Dress modestly and keep voices low, as this is an active monastic education centre.
• Duration: 20–30 minutes.
