Lancaster Castle is a medieval fortification dominating the city of Lancaster in Lancashire for over 1,000 years, most likely founded in 1092-94 upon the site of a Roman fort overlooking the River Lune crossing. Owned by the serving British monarch through the Duchy of Lancaster, the castle has witnessed some of England's most significant historical events, including the trials of the Lancashire Witches in 1612 and the imprisonment of George Fox, founder of the Quaker movement. Originally serving as a stronghold and residence, the castle later became Europe's longest-serving operational prison until its closure in 2011. Today it functions as one of Lancashire's premier heritage sites, attracting over 200,000 visitors annually with free access to its majestic courtyard and regular cultural events throughout the year.
