The Sanctuary of Truth (or Prasat Sat Ja-Tam in Thai) is a gigantic wooden building constructed according to ancient Thai ingenuity. It is covered with wooden carve sculpture and covers an area of more than two rais. The top point of the building is about 105 meters high. The sculptures in the four gopura respectively represent images from the Buddhist and Hindu religions and mythologies of Cambodia, China, India and Thailand.
The project was initiated as an idea of Thai businessman Lek Viriyaphan in 1981 who already iniated Muang Boran
near Bangkok, and is scheduled to be complete in 2025. The temple is also also called Wang Boran sometimes.
