Armoured control tower and stem both still standing

The most intact of the four light cruisers left in Scapa Flow, Köln rests on her starboard side with the shallowest steel at 22 m and the seabed at 36 m. She was never raised for scrap, so the stem, the armoured control tower and the bridge structure still read as a ship rather than as wreckage.
Also known as SMS Cöln, SMS Koln.

The dive
The wreck lies on her starboard side and runs away in both directions from the shot, with the shallowest steel at 22 m and the seabed at 36 m. Scapa Flow Wrecks calls her the most intact of the four cruisers and not a complex wreck to navigate: keep the seabed on one side and the plating on the other and the route out and back stays simple.
The features people come for are the imposing stem and the armoured control tower, both intact, with the bridge structure behind them. Because she was never raised — unusual among the Scapa ships — the shape of a 155 m cruiser survives in a way the salvaged battleships cannot offer. Scapa Flow Wrecks calls the dive well within the grasp of competent sport divers, though the seabed is at 36 m and the water is cold.

Köln — spelled Cöln when she was built — was launched on 5 October 1916 and interned at Scapa Flow at the end of the war. Rear Admiral Ludwig von Reuter believed the British intended to seize the German ships on 21 June 1919 and ordered the fleet scuttled; Köln sank at 13:50 that day. Unlike most of the fleet she was never raised for scrap, and she is the most intact of the four cruisers left in the Flow. Her wreck was declared a scheduled monument on 23 May 2001.

Questions divers ask
How deep is the SMS Köln?+
The wreck lies in 36 m of water and rises to 22 m at its shallowest point, so most of the dive sits between those two figures. It is deep and cold, but not a complex wreck to navigate.
