PHNOM PENH, Cambodia -- Archaeologists in Cambodia have unearthed a dozen centuries-old sandstone statues in a “remarkable discovery” at the Angkor World Heritage Site near the city of Siem Reap, authorities said Wednesday. The statues — depicting so-called “door guardians” — were discovered last week near the north gate leading to the 11th-century Royal Palace at Angkor Thom, the last capital of the Khmer Empire, said Long Kosal, spokesman for the Apsara National Authority, the government agency that oversees the archaeological park. Teams were assessing the ancient gate's structure and searching for fallen stones around the portal on the north side of Angkor Thom, one of four entrances to the complex, when the discovery was made.

The statues depict guardians standing at attention and vary in size from about 1 meter to 110 centimeters, or about 39 to 43 inches. They were found buried at depths of up to 1.4 meters (4.

5 feet) and some are in surprisingly good shape, with each featuring unique facial hair ornaments, adding to their distinctiveness, archaeologist Sorn Chanthorn said. “Experts believe these door guardian statues exemplify the Khneang Style, aligning with the construction period of the 11th-century palace.” the Apsara National Authority said.

Angkor Thom is part of the Angkor Archaeological Park, a complex that sprawls over some 400 square kilometers (155 square miles), named a UNESCO World Heritage Site in 1992 and one of Southeast Asia's most pop.
