I think this areas is called the Leper King Terrace on the North end of the Terrace of the Elephants in the Angkor Thom complex, north of Bayon temple (Siem Reap, Cambodia). There is a narrow pathway that winds between the wall of the terrace.

Banteay Srei temple, Cambodia. The temple is an another amazing temple in the vicinity of Siem Reap, Cambodia. Banteay Srei is fairly small, but I was definitely very glad I took a day trip (1/2 day really) from Siem Reap to here and Kbal Spean.
