Primary forms of settlements, settlement with residential walls and fortifications, solid buildings, despite their vastness, cannot be called cities. This is just a great home-estate. The city can be named, such as the settlements, where at least two housing estates, that were united under the protection walls around public places of worship. The passage between the houses, neighborhoods, public and religious buildings and fortress gate determine the maze of the city planning.

This is just a huge corral without planning organization. The only structural sense was in the walls - residential, but their extent was not in any of the planning relationship with the environment of space.
