Angkor Wat was the main temple of the ancient city of Angkor, capital of the Khmer Empire (802–1431).
The archaeological area of Angkor extents for something like 400 kilometers square. Even a week may not be enough to understand this immensity but a good bike will help you.
You are free to go almost everywhere, you may not find Indiana Jones traps but a little bit of caution doesn't hurt. Don't push movable stones.
Maybe the destiny of every great empire is to fall at some point. Somewhere in the Royal Palace.
Probably you won't see this in a "half-day Angkor tour".
Children having fun in the moat of the Angkor Wat, better don't disturb them.
I suggest the listening of this music inspired by the Americans when they came to fight in Vietnam.
You can still have the same romantic views that the French sailors had in the 19th century where plants phagocyte the ruins of a great empire. But a balance has to be reached otherwise nothing will remain.
This gate brings to the Angkor Thom, the "great city".
I met people that would stay there entire days or lives. Probably the second temple to see after Angkor Wat if you are in a hurry.
Every temple has its own secret passages, bring a torch.
As close to the equator line, the difference between day and night is very short. Darkness, as a beast, arrives really fast and no lighting is present at Angkor except the stars and the Moon.
I need to hurry.
