Launched Wilhelmshaven in 1916.  Light cruiser/mine layer displacing 5354 tons with an overall length of 490 feet (150 metres).  Like the other ships of the German High seas Fleet, she was also armour plated and heavily armed.  

She now lies off the northerly tip of Cava in 24-28 metres of water.  The least depth over her port side is about 12-14 metres.  The wreck is lying on a slope, and the deck side is about 4 metres deeper than the bottom at her keel.  Because of her shallow depth, the Karlsruhe has been more extensively salvaged and has been more exposed to the effects of winter storms.  Her stern section remains relatively intact, and her bow gun turrets can still be seen.  She is an interesting dive despite her condition, and the shallow depth means she is covered in a profusion of marine life.  The seabed near the wreck is littered with debris, as well as scallops and queenies.
