A Medieval fortress wall

Third grade pupils made a model of a fortress wall. They learned a lot of new things about ancient  medieval settlements.The villages were encircled by  walls to protect them from the attacks of enemies. That’s why these walls were stronger, higher and more impregnable. The most used material was stone. At the top of the wall there were loopholes. In the middle of the walls and in the corners rose high towers. In front of the wall  people dug trenches and filled them with water. There was a drawbridge in front of the fortress gate.
