Attraction Details : 
This monastery is the 
biggest and oldest ancient remains in Phetchaburi. It was built in 13 
A.D. when the influence of ancient Khmer culture expanded to this area. 
Originally, there were five prangs (Khmer-style pagoda) made of 
sandstone to worship accordance with Bhramanism. When the influence of 
Buddhism prevailed in the region, it was turned into a Buddhist temple. A
 Shrine hall was later constructed in the compound. Today, visitors can 
only admire the remaining three prangs which remain next to the 
sandstone walls.http://www.tourismthailand.org/See-and-Do/Sights-and-Attractions-Detail/Wat-Kamphaeng-Laeng--5234
