Description: Taken from the south with Castle Rock on the left with cave entrances above Mortimer's Hole. Former store shed, which was to be demolished not long after the picture was taken, obscures view of Rock Cottage. The caves which are found here as well as all over Nottingham are one of the most difficult and intricate problems of local archaeology. Some of them are natural; others are artificial, but date back to prehistoric times, others again are mediaeval or even modern cellars. They have always been famous, and Asser, the friend and biographer of King Alfred, writing about 900, tells us that the ancient name for Nottingham was Tiuogobauc, which he translates as meaning ' the cave dwellings.' Later etchings and pictures show the caves with windows fixed in place, used for habitation and storage. See NTGM002835 for further information on Mortimer's Hole.
