One of the evidences that can reflect an importance and prosperity of the region where the interesting Petchburi is situated must include the name of Wat Kum Pang Lang on the list. This attraction is the biggest and the most ancient historic site in Petchburi that is presumed to be built in Cambodian style during King Chaiworaman 7's reign, or about buddhist era 18-19. Other important constructions are the 3 out of 5 remaining Prangs.
