Situated in Ban Phue District, this archaeological site features a large number of ancient buildings and ancient objects of both prehistoric and historic times. They are mostly of Dvaravati, Lop Buri, and Lanchang style.
The site is located in a thriving forest called Pa Khua Nam. In addition, within the site are many rocks of peculiar shapes which resulted from glacial movement millions of years ago. It can be seen that most of the ancient buildings and objects found in this area were modified from what was naturally available and not built entirely by human beings. For instance, a rock was decorated to make a stupa or was chiseled into the shape of a foot.
The site was declared a historical park by the Fine Arts Department in 1991. Archeological evidence found at the site includes Phra Phuttabat Bua Bok, Phra Phuttabat Lang Tao, Phra Phutta Bat Bua Ban, religious buildings modified from rocks, sandstone bai-sema (leaf-shaped stones marking the limits of a Buddhist temple), sandstone images and idols, cave paintings and stone axes.
Phu Phra Bat Historical Park covers the entire area of the Phra Phutthabat Bua Bok which is around 1,200 acres. In addition to the beautiful landscape, caves and caverns, rocks of different sizes and shapes dot the area. Moreover, pre-historic paintings over cliff faces have been discovered, although many leave only the faintest of traces.
Visitors are recommended to explore Tham Non Sao Ae, Tham Woa Daeng, Tham Chang, and Tham Sung to see the paintings that depict the livelihood of pre-historical community which can be traced back to approximately 2,500-3,000 years ago.
The sandstone bai-sema, sandstone images and idols of Dvaravati era are also discovered at Poeng Hin Po Ta Luk Koei.
Admission fee is 100 baht.
