Angkor Wat is the world renowned wat (temple) in Angkor World heritage site and was built in the early 12th Century.
Originally for Hindu’s but later with the king converting to Buddism the use of the temple changed during the construction.
The outer walls of the temple 3.6km long and has the moat going around that. The temple itself is approximately 1.5km x 1.2km so it takes quite a while to walk around! Within the temple surround walls includes all resources needed for the worlds largest community (at the time).
The Angkor world heritage area was the first in the world to support 1 million inhabitants at one time (London in the same era had a mere 40,000 people population). It comprises of many temples of different eras (700-1300AD).
I visited Angkor Wat (the biggest one with the moat around it), Angkor Thom area with Bayon Wat (The ones with all the faces carved into the stone), Preah Khan (The one with the trees growing out of the walls) and another one that translates in English to Elephant Temple, as it is decorated with Elephant carvings.
Leaving the Angkor Wat I came across a group of people (apsara dancers) in clothing which was similar to the carvings on the walls inside the temple.
