The city wall is located in the center of the historical park in Tambon Muang Kao and surrounded by earthen ramparts. The north and the south walls are each 2,000 meters long, where as the east and the west walls are each 1,600 meters long. The walls contain four main gates: Sanluang on the north, Namo on the south, Kamphaenghak on the east, and Oar on the west. A stone inscription mentions that King Ramkhamhaeng set up a bell at one of the gates. If his subjects needed help, they would ring the bell and the King would come out to settle disputes and dispense justice.
Inside the town stands 35 monuments including Buddhist temples and many other structures.
