Ruthin (not to be confused with Rhuddlan, also in Clwyd) is a late 13th century castle built during Edward I's first campaign against the Welsh. The site may have been used by an earlier Welsh castle, possibly a residence of Llewelyn the Great. If so, that earlier castle was partly incorporated into Edward's new fortifications. Castle Street,

One of the best earthwork castles in Wales, Tomen-y-Rhodwydd is a motte and bailey defensive enclosure, with a rampart and ditch, built in 1149 by Owain Gwynedd to exert control over north Powys. The Welsh lord also intended his fortification to be a strategic site that would enable him to seize the rich lands east of the River Clwyd up to the Dee estuary.
Twthill Castle is the first castle at Rhuddlan, an earthen motte, or castle mound, built by Robert of Rhuddlan in 1073 on a spur of land overlooking the River Clwyd. Robert chose a site traditionally thought to be the site of an earlier royal palace of Gruffud ap Llewelyn. Robert of Rhuddlan was a former squire at the court of Edward the Confessor, who rose to gain control over all of north Wales beyond the River Clwyd. Castle Street,
