Phra Datu Chedi Luang dates back over 600 years and is the tallest Pagoda in the whole of Thailand.
During the reign of Tilokaraja, 9th Monarch of the Mangrai dynasty,(1441-1487), the Chedi was reconstructed and enlarged to 80 metres high and 56 meters on each side of the base.
Chedi Luang is a mix of La Na , Sri Lankan and Pagan architecture.
The most important alteration was of a niche on the Eastern aspect of the Chedi, where The Emerald Buddha was enshrined for 79 of its 80 years in Chiang Mai.
Further reconstruction during the reign of Phra Muangkeo, 11th Monarch of the Mangrai Dynasty, (1495-1525), strengthened and enlarged the base and walled enclosures were added.
In 1545, during the reign of Queen Chiraprabha, the 15th Monarch of the Mangrai Dynasty, Chiang Mai suffered a heavy rainstorm and earthquake causing half of the Chedi to crumble. Restoration impossible, it was left like this for 400 years.
In 1990, the Thai Government gave a budget of 35,000,000 baht for restoration of the ruins of Chedi Luang. The work was completed in December 1992 and the Chedi now sits at 60 metres wide at the base. The collapsed upper section not restored, the exact height is not known.
