It is administrated by Cumberland Council, which covers an area similar to the historic county of Cumberland. Carlisle's early history is marked by the establishment of a settlement called Luguvalium to serve forts along Hadrian's Wall in Roman Britain. Due to its proximity to Scotland, Carlisle Castle and the city became an important military stronghold in the Middle Ages. The castle served as a prison for Mary, Queen of Scots in 1568 and currently hosts the Duke of Lancaster's Regiment and the Border Regiment Museum. A priory was built in the early 12th century, which subsequently became Carlisle Cathedral in 1133 on the creation of the Diocese of Carlisle. As the seat of a diocese, Carlisle therefore gained city status. Carlisle also served as the county town of Cumberland from the county's creation in the 12th century.
