List of Medieval Urban Defences (Town Walls and Ditches) in Wales

Town walls, banks and gates. Those built by the Romans, Anglo-Saxons or Danes are mentioned if they were maintained, at least partly, during the period 1000-1600. As with most fortifications of the period these were not simply defensive but also reflected social status. Ambitious town leaders would petition for and build walls for the personal and civic kudos. Walls and ditches, or sometimes just isolated gates, also regulated trade and made collection of taxes easier. Some villages, in vulnerable areas, had simple defences of ditches to deter cattle raiders and 'wolves' (Although it is doubtful wolves were a significant threat, to any community at any time, they were believed to be a threat and had enormous psychological power).
