The old inner city was enclosed by a rectangular wall about 1.8 kilometers by 1.4 kilometers. The walls consist of two earthen berms and a third wall made of earth but cased in laterite. Water filled the space between the three walls. A single gate in each wall controlled access to the city. Three of the gates were fortified.

The eastern third of the old inner city is occupied by modern buildings, mostly small shops, guest houses and the homes of those who make their livings off the visitors to the historical park. The historical structures are clustered around the center of the inner city.
