Basingwerk Abbey abbey was founded in 1132 by Ranulf de Gernon, 4th Earl of Chester, who had already brought Benedictine monks from Savigny Abbey in southern Normandy. Likely the first location of the abbey was not at the current location at Greenfields but at the nearby Hen Blas. The abbey became part of the Cistercian Order in 1147.
The abbey had significant lands in the English county of Derbyshire. Henry II gave the monks a manor near Glossop. The Monks' Road and the Abbot's Chair near the town are a reminder of the Abbey's efforts to administer their possession. In 1290 the Abbey gained a market charter for Glossop. The monks also got another charter for nearby Charlesworth in 1328.
By the 13th century, the abbey was under the patronage of Llywelyn the Great, Prince of Gwynedd. His son Dafydd ap Llywelyn gave St Winefride's Well to the abbey. The monks harnessed the power of the Holywell stream to run a corn mill and to treat the wool from their sheep. In 1433, the monks leased all of Glossopdale in Derbyshire to the Talbot family, the future Earls of Shrewsbury (1442).
In 1536, abbey life came to an end with the Dissolution of the Monasteries during the reign of Henry VIII. Its dissolution was made lawful by the Dissolution of the Lesser Monasteries Act and the lands of the abbey were granted to lay owners.
The abbey ruins are part of Greenfield Valley Heritage Park, and are managed by Cadw. The abbey marks the starting point of the North Wales Pilgrims Way.
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.
