Task: Question Generation
Input (English): Passage: Brougham Castle (pronounced ) is a medieval building about 2 miles (3.2 km) south-east of Penrith, Cumbria, England. The castle was founded by Robert I de Vieuxpont in the early 13th century. The site, near the confluence of the rivers, Eamont and Lowther, had been chosen by the Romans for a Roman fort called Brocavum. The castle is scheduled as an Ancient Monument, along with the fort, as "Brougham Roman fort and Brougham Castle".In its earliest form, the castle consisted of a stone keep, with an enclosure protected by an earthen bank and a wooden palisade. When the castle was built, Robert de Vieuxpont was one of the only lords in the region who were loyal to King John. The Vieuxponts were a powerful land-owning family in North West England, who also owned the castles of Appleby and Brough. In 1264, Robert de Vieuxpont's grandson, also named Robert, was declared a traitor, and his property was confiscated by Henry III. Brougham Castle and the other estates were eventually returned to the Vieuxpont family, and stayed in their possession, until 1269, when the estates passed to the Clifford family through marriage.
With the outbreak of the Wars of Scottish Independence, in 1296, Brougham became an important military base for Robert Clifford, 1st Baron de Clifford. He began refortifying the castle: the wooden outer defences were replaced with stronger, more impressive stone walls, and a large stone gatehouse was added. The importance of Brougham and Robert Clifford was such that, in 1300, he hosted King Edward I of England at the castle. Robert's son, Roger Clifford, was executed as a traitor, in 1322, and the family estates passed into the possession of King Edward II of England, although they were returned once his son Edward III became king. The region was often at risk from the Scots, and in 1388, the castle was captured and sacked.
