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 Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
