Montgomery Castle is one of many Norman castles on the border between Wales and England. The original motte and bailey is now known as Hen Domen and was built at the order of Roger de Montgomery, Earl of Shrewsbury, sometime between 1071 and 1074. After the rebellion of his son Robert of Belleme in 1102, the castle was given to Baldwin de Boulers. The de Boulers (later known as Bowdler) family held the castle until 1214, when it was destroyed by Prince Llywelyn ab Iorwerth.
The rebuilding of Montgomery Castle in stone was commenced in the late summer of 1223 on the 16th birthday of Henry III of England, a mile to the south-east of the original site. Its architect was Hubert de Burgh, who also rebuilt Skenfrith Castle, Grosmont Castle and White Castle in the Welsh Marches. From 1223 until 1228 masons worked solidly building the entire inner ward, or donjon as it was then known, on a great rock above the later town of Montgomery. This work consisted of the gatehouse, two D-shaped towers and the apartments which crowded around the curtain wall of the inner ward. After an unsuccessful attack by Prince Llywelyn ab Iorwerth in 1228, the middle and outer wards were added; another attack in 1233 resulted in damage to the well tower, which had to be subsequently repaired and re-roofed.
The walled town of Montgomery was attacked by the forces of Owain Glyndŵr in 1402 and sacked and burned. The local forces successfully defended the castle and the town remain a ruin until the early 17th century.
When the First English Civil War began in August 1642, Mid Wales was largely Royalist and the castle held for Charles I by the elderly Lord Herbert of Cherbury. In September 1644, he surrendered to Parliamentarian troops commanded by Sir Thomas Myddelton and Thomas Mytton. On 18 September, a Royalist attempt to retake the castle was repulsed in what was the biggest battle of the war in Wales and a major victory for Parliament. However, the new Parliamentarian governor Sir John Pryce, a Royalist defector, switched sides again in May 1645.
Much of Wales rose again in the 1648 Second English Civil War and the castle walls were demolished by Parliament in June 1649, despite opposition from the 2nd Lord Herbert, who succeeded his father in 1648. This policy was followed throughout England and Wales to prevent them being used again, reducing the number and cost of garrisons required. He was the last to use the castle as a residence and was buried at Montgomery in 1655.
There are permanent exhibitions relating to the medieval Hen Domen and Norman Montgomery Castles and their archaeological excavations with scale models of both in The Old Bell Museum, Montgomery, Powys.
References:Doune Castle was originally built in the thirteenth century, then probably damaged in the Scottish Wars of Independence, before being rebuilt in its present form in the late 14th century by Robert Stewart, Duke of Albany (c. 1340–1420), the son of King Robert II of Scots, and Regent of Scotland from 1388 until his death. Duke Robert"s stronghold has survived relatively unchanged and complete, and the whole castle was traditionally thought of as the result of a single period of construction at this time. The castle passed to the crown in 1425, when Albany"s son was executed, and was used as a royal hunting lodge and dower house.
In the later 16th century, Doune became the property of the Earls of Moray. The castle saw military action during the Wars of the Three Kingdoms and Glencairn"s rising in the mid-17th century, and during the Jacobite risings of the late 17th century and 18th century.
