Wat Phra That Chedi Luang, located within the ancient city of Chiang Saen in Chiang Rai province, is one of the most important historical sites reflecting the flourishing of early Lanna civilization. Chiang Saen was once a crucial political, religious, and cultural center in the upper Mekong River basin. This temple thus plays a vital role as a sacred site and a historical landmark showcasing the architectural styles and Buddhist beliefs of the past.

The Phra That Chedi Luang is a Lanna-style bell-shaped stupa, situated on a multi-tiered, raised square base – a style found in classical Lanna art. Its overall appearance reflects a blend of Theravada Buddhism and unique Lanna construction styles. Despite the passage of time and deterioration, the main structure clearly shows its past grandeur.

Historical evidence and archaeological studies indicate that the temple likely dates back to the 19th–20th centuries CE, when Chiang Saen was a significant city of the Lanna Kingdom. However, there is no official documentation specifying the builders, making this information more of a "historical assumption" than a definitive identification of individuals.

Remains of old buildings and the foundations of old viharas (assuming buildings) can still be found within the temple grounds. This provides a relatively clear view of the historical layout of the religious site. The surrounding atmosphere is peaceful and serene, ideal for studying history, art, and ancient architecture, as well as for cultural tourism that emphasizes learning rather than entertainment. Wat Phra That Chedi Luang is therefore considered one of the important destinations for those interested in Lanna civilization and the history of Chiang Saen.
