Numerous caves exist in the sandstone underneath Nottingham, including the spectacular 322-foot-long Mortimer's Hole directly below the castle.
Part of the excellent City of Caves attraction, this particular formation takes its name from Roger Mortimer, lover of Queen Isabella, wife of Edward II (legend has it Mortimer once hid here from the jealous king).
In all, more than 450 caves lie beneath Nottingham, the largest known grouping of caves in the country, and have been used for centuries for storage and defense.
