Wat Phra Mahathat Vihan is the most important temple of Nakhon Si Thammarat and southern Thailand. It was constructed at the time of the founding of the town, and contains a tooth relic of Lord Buddha. The 78-meter-high chedi is surrounded by 173 smaller ones. While the chedi is in Sri Lankan style, it is said to have been built earlier in Srivijaya style. At the base of the chedi is a gallery named Wihan Tap Kaset, decorated with many Buddha statues and elephant heads emerging from the chedi.
