Angkor Wat
This 12th century complex was not only a temple, but also a city. It consists of almost 200 hectares most of which would have been the city. Two causeways cross the large moat surrounding the complex, where you pass through the outer enclosure. The temple itself is a three tiered pyramid, each level having it's own galleries or walled enclosures and towers. We only spent a couple of hours here, but several days would hardly do it justice.
