via Phnom Penh Post, 01 July 2022: Not sure if this is the same stone that was earlier described as a foundation stone.
The Apsara National Authority (ANA) announced that their working group in charge of restoration work at Angkor Thom’s Takav Gate or the West Gate recently found an ancient stone slab commonly known as a boundary stone.
The boundary stone is 53 cm by 53 cm and 12 cm thick and is covered with thin sheets of gold. It was found at the Takav Gate when the upper part of the gate’s structure was dismantled for restoration work.
“On the stone slab, there are many holes – a large round hole in the center of the stone surface, surrounded by square holes in all eight directions and in the northeast corner, which all have significance in traditional Khmer beliefs from ancient times to the present,” the ANA said.
