Kampaeng Yak Wall

The legend has it that giant wall, which is 15 kilometres long, was erected in the 9th century by the ancient Sikhottabong Kingdom. Some say, however, that it is a natural sandstone formation which was incorporated into the civilization's defense system.

The best place to visit the Giant Wall is 8 km north of Thakhaek on Route 13 where is reaches a height of 16 meters with an unbroken section 75 meters long. Here there is a small shrine constructed by the French that contains a statue of the Virgin Mary.
