Almost in the centre of Chiang Mai are the remains of a massive chedi that toppled in the great earthquake of 1545. The temple was originally constructed in 1401 on the orders of King Saeng Muang Ma. In 1454, reigning King Tilo-Garaj enlarged the chedi (pronounced jedee) to a height of 86 m. After the earthquake, the chedi lay in ruins until 1991-92, when it was reconstructed at a cost of several million baht. A magnificent testament to Lanna (northern Thai) architecture and art, restored sections hint at its former glory. Wat Chedi Luang is also home to the "Pillar of the City", a totem used in ancient Thai fertility rites.
