Castelnau
At the end of the Early Middle Ages, two buildings made people want to live in a town. These were the castle and the church. During this time period, there were types of towns called "castra," "castet," "forts," and "castelnaus". They were said to be fortified settlements with a stone castle inside. Castelnaus were usually made up of many houses in the center. Castelnaus were usually on defensive places at higher elevations.
