Trang province is located in the South near the West Sea of Thailand. It is adjacent to Andaman Sea and Indian Ocean and has been the important seaport of the south from past to present in which its history has been developing in sequence as follows:

A great deal of archaeological evidence was discovered in caves such as cracked stone axes, polish axes, earthenware, three-legged pots, steel equipment, color paintings in Khao Sam Batr cave, Khao Sai cave, Khao Ku Ram cave, Khao Pi Na cave which is a lone hill at Trang river, Khao Mai Kaew cave, Khao Tiem Pa cave which is a lone hill in the middle of a field, Khao Jao Mai cave, Khao Bae Na cave at a seashore and ancient human skeletons at Wat Phu Khao Tong cave and Sa Kai cave at the side of Bun Tad hill. This shows that Trang ancestors have been living there for not less than 5,000 years.

This was the time when the Trang ancestors knew how to grow plants, to feed animals and to go out of their caves to build dwellings at the side of hills, streams, and at the middle of fields which became big communities, especially the society at the side of Trang streams at Khao Ku Ram, Huay Yod district in which the evidence has continuously been discovered since Prehistorical Era including objects showing the relationships with foreigners such as glass beads, raw clay votive tablets and stupa pieces. The raw clay votive tablets were found in several caves, for instance, Khao Sai cave, Kee Ree Vihan cave and Khao Nui cave which are located at the side of Trang river not far from Khao Ku Ram. Archeologists estimates the age of the raw clay votive tablets around 13-14 Buddhist era. The most important discovery was the archeological site at the same period at Na Pla District, Amphoe Muang Trang near Nang Noi canal which is the branch of Trang river to Bun Tad hill and to Muang Phatthalung. The site consisted of the religious building bases, stupa pieces, Avalokitesvara Samrid and so forth which its estimated age was also around the 13-14 Buddhist era. These archeological findings shows the influence of Mahayana Buddhism and Srivijaya Contemporary Art and ancient territory at the eastern part of the South, Then, around the 18 Buddhist era, Theravada Buddhism in Lanka Wong doctrines began to be widespread in the South which can be seen from Nakhon Si Thammarat history mentioning Phra Tanakuman and Ms. Hemchala from India who respectfully engaged Buddha's relics to flee from the war to Lanka and went ashore at Sai Kaew beach and buried the Buddha's relics. When Phraya Sri Thammasokraj discovered them, he decided to build the country there at Sai Kaew beach and created the stupa of the Buddha's relics as well as possessing cities in Melayu cape called 12 Zodiac. Trang is one of 12 Zodiac cities with horse badge as its city badge showing that in Nakhon Si Thammarat era, Trang was the city regulated by Nakhon Si Thammarat and continuously went on for a long time.
