SMS Markgraf
SMS Markgraf is a scuttled German battleship lying on the seabed of Scapa Flow in Orkney, Scotland, and it ranks among the most celebrated wreck diving sites in the world. It was one of the capital ships of the Imperial German High Seas Fleet interned at Scapa Flow following the armistice that ended the First World War, and it was deliberately sunk on 21 June 1919 in one of the most dramatic acts of mass scuttling in naval history. Today the wreck rests upside down in around 25 to 45 metres of water and draws experienced divers from across the globe who come to witness the eerie grandeur of a warship entombed beneath one of Scotland's most storied stretches of water.
The Markgraf was a König-class battleship launched in 1913 and commissioned into the Imperial German Navy in 1914. Displacing approximately 25,000 tonnes and stretching over 175 metres in length, she was one of the most powerful warships of her era. She served at the Battle of Jutland in May and June 1916, where she sustained damage during the largest naval battle of the First World War. Following Germany's defeat, the High Seas Fleet was ordered to Scapa Flow under the terms of the Armistice, and 74 German warships were interned there under British guard. Rear Admiral Ludwig von Reuter, believing that peace negotiations had broken down and determined to prevent the ships from being seized by the Allies, gave the order to open the seacocks and flood the fleet simultaneously. The Markgraf was one of the last vessels to sink, going down in the early afternoon of that extraordinary June day in 1919.
Diving the Markgraf is considered one of the more challenging and rewarding experiences in British wreck diving. The ship lies inverted, with her keel at around 25 metres and her superstructure extending down to approximately 45 metres, meaning significant portions of the dive fall within decompression stop territory and require careful gas management. The hull is encrusted with decades of marine growth — soft corals, plumose anemones, and various sea creatures have colonised the metal surfaces — creating an otherworldly palette of colour against the dark grey steel. Visibility in Scapa Flow is often surprisingly good by UK standards, and on a clear day natural light penetrates the shallower sections in shimmering curtains that illuminate the vast curved hull in an almost theatrical way.
Scapa Flow itself is a natural harbour formed by the Orkney mainland and several of the larger islands, including Hoy, South Ronaldsay, and Burray. It has an extraordinary strategic history stretching back far beyond the First World War and served as the principal anchorage of the British Grand Fleet during both world conflicts. The landscape above the water is quintessentially Orcadian — wide open skies, rolling moorland, dramatic clifftops, and the ever-present sound of seabirds and wind. From the surface, where dive boats typically moor using buoys over the wreck site, there are sweeping views across the flow to the reddish sandstone hills of Hoy, including the iconic Old Man of Hoy sea stack visible on a clear day.
Access to the wreck is exclusively by boat, and several well-established dive charter operators based in Stromness and St Margaret's Hope offer guided trips to the Markgraf and the other Scapa Flow wrecks. Stromness is the primary hub for Scapa diving and is reached either by the Northlink Ferries service from Scrabster near Thurso, or by flying into Kirkwall Airport from Edinburgh, Glasgow, Inverness, or Aberdeen. The Markgraf is considered one of the more advanced dives in Scapa Flow due to its depth, and most operators require evidence of appropriate certification and experience before allowing divers to descend to the deeper sections. The best conditions are generally found between April and September, when longer daylight hours and calmer weather make boat operations more comfortable, though Scapa can be dived year-round by those willing to contend with colder water and rougher surface conditions in winter.
The wreck carries significant historical protection under UK law and is designated under the Protection of Military Remains Act 1986, which means it is classified as a protected place. Diving is permitted for recreational purposes, but the removal of any artefacts is strictly prohibited. An important and poignant distinction of the Markgraf compared to some other Scapa wrecks is that she was never salvaged — companies such as Cox and Danks raised a number of the smaller vessels and some of the larger battleships during the 1920s and 1930s, but the Markgraf, along with the König and the Kronprinz Wilhelm, proved too deep and too massive for the salvage operations of the era and remains largely intact on the seabed. The men who died during the scuttling — nine German sailors shot by British guards during the chaos of that June afternoon — are remembered as part of the complex human story of the wreck.
For non-divers, Scapa Flow and the story of the scuttled fleet can be explored through the Stromness Museum and the Scapa Flow Visitor Centre and Museum on the island of Hoy, which together provide vivid accounts of the internment and the scuttling through artefacts, photographs, and film. The waters above the Markgraf can also be enjoyed by snorkellers in the shallower sections, and boat trips are sometimes available for those who simply wish to experience the landscape of the flow and understand its remarkable layered history. Scapa Flow remains one of those rare places where the weight of the past is almost physically palpable, where the boundary between historical imagination and direct encounter with evidence is dissolved by the presence of the ships themselves, still lying where they went down more than a century ago.
