Surrounded by walls and a moat, the walled city of Angkor Thom is a staggering undertaking built in the late 12th century as the new capital of the Khmer Empire. Measuring around 3 kilometers per side and containing many of Angkor's most renowned temples, the size and scope of this square city perfectly enclosed by a moat is undoubtedly up there with Angkor Wat as a wonder of civilization. Reaching Angkor Thom requires crossing an ancient bridge over the moat, one for each direction. The south causeway leading is the most atmospheric and best preserved, lined with a dramatic row of giant stone warriors and demons holding a giant naga snake, forming a magnificent ceremonial entrance to Angkor Thom. The north and west causeways feature parallel rows of gods and demons holding the naga, creating equally stunning approaches, though more susceptible to the claws of time.

Today, wandering within the walls of Angkor Thom offers a glimpse into the grand vision for an imperial capital. The causeways still serve as pathways into another era, one of god-kings and stone cities. While mostly deserted now, Angkor Thom remains the anchor of the sprawling Angkor complex, and days can be had just exploring the remnants inside, highlighted by Bayon. Overall, Angkor Thom’s crumbling bridges, vast waterways and grand constructions evoke the vast scale and wealth from Angkor's golden age.
