Ruthin - Human settlement in Wales

"Ruthin is the county town of Denbighshire in north Wales and a community in the southern part of the Vale of Clwyd. The older town, the castle and St Peter's Square lie on a hill, but many newer parts in the flood plain of the River Clwyd. This emerged several times in the late 1990s – flood-control works costing £3 million were completed in autumn 2003. Ruthin is skirted by villages such as Pwllglas and Rhewl. The name comes from the Welsh words rhudd (red) and din (fort), reflecting the colour of the sandstone bedrock, of which the castle was built in 1277–1284. The original name was Castell Coch yng Ngwern-fôr. The mill is nearby. Maen Huail is a registered ancient monument attributed to the brother of Gildas and King Arthur, located outside Barclays Bank in St Peter's Square. - Wikipedia"
