In 1136, early in the Anarchy, Rougemont Castle was held against King Stephen by Baldwin de Redvers.
Redvers submitted only after a three-month siege, not when the three wells in the castle ran dry, but only after the exhaustion of the large supplies of wine that the garrison was using for drinking, baking, cooking, and putting out fires set by the besiegers.
To distinguish the two, the Romans also referred to Exeter as ) When the fortress was abandoned around the year 75, its grounds were converted to civilian purposes: its very large bathhouse was demolished to make way for a forum and a basilica, and a smaller-scale bath was erected to the southeast.
but could not be maintained for public view owing to its proximity to the present-day cathedral.
During the high medieval period, both the cathedral clergy and the citizens enjoyed access to sophisticated aqueduct systems which brought pure drinking water into the city from springs in the neighbouring parish of St Sidwell's.
For part of their length, these aqueducts were conveyed through a remarkable network of subterranean tunnels, or underground passages, which survive largely intact and which may still be visited today. In 1549, the city successfully withstood a month-long siege by the so-called Prayer Book rebels: Devon and Cornish folk who had been infuriated by the radical religious policies of King Edward VI.
The city is on the River Exe about 37 miles (60 km) northeast of Plymouth and 70 miles (110 km) southwest of Bristol.
However, William quickly arranged for the building of Rougemont Castle to strengthen Norman control over the area.
Properties owned by Saxon landlords were transferred into Norman hands and, on the death of Bishop Leofric in 1072, the Norman Osbern Fitz Osbern was appointed his successor.
In 1001, the Danes again failed to get into the city, but they were able to plunder it in 1003 because they were let in, for unknown reasons, by the French reeve of Emma of Normandy, who had been given the city as part of her dowry on her marriage to Æthelred the Unready the previous year.
Two years after the Norman conquest of England, Exeter rebelled against King William.
