Castell Dinas Brân is a medieval castle, built by the Princes of Powys Fadog, which occupies a prominent hilltop site above the town of Llangollen in Wales.
During the British Iron Age, around 600 BCE, a large hillfort was built on the summit of what was to become Dinas Brân by a Celtic tribe named the Ordovices. The earliest structure that might have been built at Dinas Brân is believed to have belonged to Elisedd ap Gwylog during the 8th century. Elisedd, who was a Romano British ruler during the Anglo-Saxon settlement of Britain is named on the Pillar of Eliseg and is considered one of the founders of the Kingdom of Powys, however, no archaeological evidence for any structure from this period has been found.
The presently visible stone castle was probably built in the 1260s by Gruffydd Maelor II, a prince of Powys Fadog, on the site of several earlier structures. Following the end of the Conquest of North Wales by King of England, most of Powys Fadog including the castle was granted to John de Warenne, Earl of Surrey. Rather than rebuild Dinas Brân, De Warenne choose instead to build a new castle by the River Dee at Holt on the Flintshire-Cheshire border. Dinas Brân was left to fall into ruin.
Dinas Brân has rectangular stone defensive walls with the longer sides running in an east-west direction. The northern wall is defended with the steep natural slope that falls sharply downwards for several hundred feet. The walls on the gentler slopes on the southern and eastern sides are strengthened with an additional rock-cut ditch and counterscarp bank.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
