The largest preindustrialised city in the world

Mayans eat your heart out (and they probably would), because Angkor Wat and the surrounding temples are awesome. This place is seriously MASSIVE. And they let you climb all over them - health and safety guidelines don't get a look in. We spent a day and a half visiting (what our knowledgeable tuk-tuk driver informed us were) the best ones, but you could probably spend a week here and still not see them all (if you could stand the heat that is).
