The Angkor temple complex was the capital of the Khmer Empire which flourished from around the ninth to the fifteenth century. There are many temples of various age and in different states of decay. This figure guards one of the main gates into the old "city".
Here's the road leading up to the gate. Here you can see the figures in situ. They flank the entrance on both sides. I can imagine this was a very impressive sight for visitors back in the old days (and even now!). Photos taken in December 2016.
