The Pillar of Eliseg, also known as Elise's Pillar, stands near Valle Crucis Abbey, Denbighshire. It was erected by Cyngen ap Cadell (died 855), king of Powys in honour of his great-grandfather Elisedd ap Gwylog. The form Eliseg found on the pillar is assumed to be a mistake by the carver of the inscription.
Whilst the pillar itself dates to the 9th century, the large artificial mound is thought to be significantly older, possibly prehistoric. Certainly the mound can be dated to the Bronze Age.
The Latin inscription consisted of some thirty-one lines of insular script. It not only mentioned several individuals described in the Historia Britonum, but also complemented the information presented in that text. The inscription is one of the longest surviving inscriptions from pre-Viking Wales.
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.
