Except at the corners, which were fashioned of stone slabs arranged much like the corner of a brick wall, the stones were of no uniform size or pattern. Generally, however, they were wedge-shaped and were placed with the smaller end of the wedge at the surface and the larger on the inside. This arrangement held them locked in position by their own weight and made them resistant to earthquakes. It also necessitated giving the wall a curve, and records show that this was geometrically determined. The basic earthen wall was known as a doi and the finished wall of stone as an ishigaki. Since no mortar was used to hold the stones in place, free drainage of water was permitted. Nevertheless, openings for drainage were used, although they were kept small so as not to be of advantage to the enemy.\"§REF§(Kirby 1962) John Kirby. 1962.

The grid-pattern city form was inspired by Chinese planning precedents, and included gates or walled enclosures. Mountain fortresses appear to be an indigenous form, and were typical of remote areas. Plateaus or plains often utilized the palisade, a semi-permanent defense. Typical defenses included a rampart, a ditch, and a palisade. Grid-pattern cities were surrounded by walls that served as a demarcation point rather than as true protection, and eventually such barriers disappeared.' §REF§Deal, William E. 2005.

On the ramparts, in certain places gangling [kuang-lang, kouang-lang] trees have been planted. At regular distances are found empty casemates. The inner side of the wall is like a ramp wider than ten fathoms. On top of each ramp are huge doors, closed at night, and open in the morning.
