There has been a fortification at the same site in Lancaster since the Roman era. In 1796 the then castle was altered to include a prison and court. Since then the prison was used right up until 2011, the court rooms are still in use and are the oldest serving courts in England. My photo shows some of the recent cells only vacated when the prison was closed two years ago for cost saving reasons. Daily tours of the castle are available including the courts (when not in session) and the old/more modern prison sections. Famous prisoners in the castle include the Pendle Witches and Jacobite rebels.
