The term Derby Gaol historically refers to the five gaols in Derby, England. Today, the term usually refers to one of two tourist attractions, the gaol which stood on Friar Gate from 1756 to 1846 and the cells of which still exist and are open to the public as a museum, and the 1843 to 1929 Vernon Street Prison whose impressive frontage can still be seen today.
