Bolton Castle is a 14th-century castle located in Wensleydale, Yorkshire, England (). The nearby village of Castle Bolton takes its name from the castle. The castle is a Grade I listed building and a Scheduled Ancient Monument. The castle was damaged in the English Civil War, and “slighted” afterwards, but much of it survived. It has never been sold and is still in the ownership of the descendants of the Scrope family. History The castle was built between 1378 and 1399 by Richard, 1st Baron Scrope of Bolton, and is an example of a quadrangular castle. The licence to build it was granted in July 1379 and a contract with the mason John Lewyn was made in September 1378. Construction was reputed to cost 18,000 Marks. The 16th-century writer John Leland described 'An Astronomical Clock' in the courtyard and how smoke was conveyed from the hearth in the hall through tunnels. Bolton Castle was described by Sir Francis Knollys as having 'The highest walls of any house he had seen'. In 1536 John, 8th Baron Scrope supported the Pilgrimage of Grace rebellion against the religious reforms of King Henry VIII and gave Adam Sedbar, Abbot of Jervaulx sanctuary in the castle. In consequence John Scrope had to flee to Skipton pursued by the King's men but Abbot Sedbar was caught and executed. In retribution the king ordered Bolton castle to be torched, causing extensive damage. Within a few years, some of the damage had been repaired and Sir John had regained his seat in Parliament. Mary, Queen of Scots, at Bolton Mary, Queen of Scots was held prisoner at Bolton for six months. The story goes that she escaped and made her way towards Leyburn only to lose her 'shawl' on the way, hence the name ('The Shawl') of the cliff edge that runs westward out of Leyburn and is a well-known spot for easy walks with excellent views. After her defeat in Scotland at the Battle of Langside in 1568 she fled to England, posing a threat to the position of the Protestant Queen Elizabeth I. Mary was initially held at Carlisle Castle under the watch of Henry, 9th Baron Scrope, but Carlisle proved unsuitable and in July 1568 Mary was moved to Bolton. Her primary keeper at this location was Sir Francis Knollys who described the castle, appraising its security;This howse appeareth to be very strong, very fayre,
