Udon Thani Province is one of them. Udon Thani Province is considered the center of transportation and tourism in the northeastern region of Thailand at present. It is very important in terms of history because it is the location of Ban Chiang civilization, which is one of the oldest traces of human civilization in the world. There are many tourist attractions such as the Red Lotus Sea, Kham Chanod, which is a sacred place that the locals respect and it is believed to be the mouth of the underworld with a legend about the Naga according to the beliefs of the Isan and Lao people. There is the shrine of Pu Sri Sutho and the sacred well, Wat Pa Phu Kon, which is in the Na Yuang and Nam Som National Forest Reserves. Inside the temple, there are relics of the Lord Buddha enshrined in the Phra Ruang Rojan Si Burapha’s crown, in front of the Phra Pathom Rattana Buraphachan Maha Chedi, and the Reclining Buddha Lokanath Satsada Maha Muni, a reclining Buddha made of white marble from Carrara, Italy, 20 meters long.
