Please make some time to take this guided walk. Our tour guide, Caroline, was a mine of information, facts, dates, murders & local legend. The tour lasts about 2 hours and leaves from outside the cathedral, though you do need to book in advance at the Guildhall. There isn't too much walking involved but you do cover some very interesting areas that perhaps would just walk by without a second glance. It makes the history so real and I would highly recommend this tour.
