Wat Chedi Luang is a historic Buddhist temple located in the old city of Chiang Mai, in northern Thailand. Constructed in the 14th century during the reign of the Lanna Kingdom, it was once one of the tallest structures in the region and a major religious centre.

The temple is best known for its massive ruined chedi (stupa), which was partially damaged by an earthquake in the 16th century. Despite its ruined state, the stone structure remains an imposing and atmospheric landmark, with intricately carved elephant figures and weathered brickwork that reflect its former grandeur. The surrounding complex includes smaller temple buildings, prayer halls, and a sacred pillar known as the City Pillar (Sao Inthakin), which holds deep spiritual significance for local residents.

Today, Wat Chedi Luang remains an active place of worship as well as a key cultural and historical attraction. Visitors come to admire its ancient architecture, learn about Lanna history, and experience Buddhist ceremonies and monk interactions. Its combination of sacred tradition and visible history makes it one of Chiang Mai’s most important temple sites.
