The Ness Battery, Hoy Sound, Orkney

Orkney is well known for prehistoric archaeology and indeed maritime remains from both world wars. Perhaps less well known are the WWI and WWII heritage sites that still exist on land.

Situated on Hoy Sound, Ness Battery guarded the western entrance to the naval base of Scapa Flow, Orkney. The site itself comprised several gun emplacements, searchlight positions, AA gun positions and a huge command centre which had the task of halting any hostile move through the Hoy Sound.

The impressive Ness Battery was the subject of a visit by our students last week. Guided through the complex by Andy Hollinrake, the students were given the full history of the site including stories of the personnel that worked to guard the Royal Navy warships anchored in Scapa Flow.

Andy related how each ship that appeared on the western approaches to Hoy Sound were signalled and ordered to stop and await inspection before sailing into the naval base. On one occasion the ferry from the Scottish mainland failed to stop when hailed and so was treated to a salvo of fire from the guns in the battery. The skipper soon heeded the signal, turned round and headed back to the mainland. Andy further elaborated on the story by saying that the gun loaders were so well trained that they could fire at such a rate that 3 or 4 shells could be in the air at once!

IMG_3896The huge, concrete protected gun positions were impressive in themselves, but in a way, the surviving huts (the only surviving examples of coast battery huts present in Britain) were even more impressive as they allowed us to glimpse into the lives of the men who operated this site. The Mess Hall was extraordinary as its walls were covered with an amazing mural depicting English rural life-complete with a windmill, half-timbered houses, wooded lanes and even a gypsy encampment.

A brilliant field visit and our thanks go to Andy Hollinrake for his on-site lecture and tour!

Diving on the German High Seas Fleet Scrap Sites – Scapa Flow, Orkney

Last Friday marine archaeologists from Orkney Research Centre for Archaeology (ORCA), the University of the Highlands and Islands Archaeology Institute and colleagues from SULA Diving completed a dive on the German High Seas Fleet scrap sites.

Under a clearing blue sky, the team sailed out into Scapa Flow, Orkney on board the MV Halton to complete the second phase of the German High Seas Fleet Scrap Sites project.

Concentrating on sites located through side scan sonar survey completed in phase one, the archaeologists recorded and documented extensive remains of the First World War fleet that still lie on the seabed. The conditions underwater were perfect and visibility was good, allowing the divers to take some excellent photographs and video footage while recording and surveying the wreckage left behind following the inter-war salvage efforts on the scuttled German High Seas Fleet.

Archival research will shed further light on the debris itself and will identify from which ships the wreckage originated.

rpa_0682The salvaging of the German High Seas Fleet in the 1920s-40s raised battleships, battlecruisers and destroyers from the seabed for scrapping at dockyard sites further south such as Rosyth. Today the remains of these ships and their associated salvage lie on the seabed, continuing to tell the story of the High Seas Fleet in Scapa Flow, and providing an exciting and interesting heritage resource.

The project is designed to showcase the significant wreckage of the scrap sites of the German High Seas Fleet and was conducted on behalf of Historic Environment Scotland.

German High Seas Fleet Scrap Sites to be Surveyed

Scapa Flow: View from Hoy looking across to Stromness

The wrecks of the First World War German High Seas Fleet that lie on the seabed in Scapa Flow, Orkney are renowned as one of most famous wreck diving sites in the world.

These wreck sites also provide marine archaeologists with an unparalleled insight into the construction of warships from this period.

Archaeologists from the University of the Highlands and Islands Archaeology Institute have teamed up with  SULA Diving to undertake a Historic Environment Scotland funded project on the salvage sites of the scuttled wrecks of the High Sea Fleet.

The High Seas Fleet was interned at the Royal Navy base Scapa Flow, Orkney at the end ofsites the First World War. Admiral Ludwig Von Reuter, believing the armistice was over, ordered the fleet to be scuttled. This resulted in the sinking of 52 of the 74 interned vessels. After the scuttling, 45 of these vessels were salvaged and various components of the ships’ structures lie on the seabed marking these wreck sites, a cultural heritage resource that is relatively undocumented. Today, the 7 wrecks that were not salvaged constitute one of the most famous wreck diving sites in the world.

The project is led by Sandra Henry (Marine Archaeologist, University of the Highlands and Islands Archaeology Institute) and Kevin Heath (SULA Diving) on behalf of Historic Environment Scotland and aims to identify the locations of the primary scrap sites and associated secondary sites from the salvaging of the German High Seas Fleet.

The secondary scrap sites were created as the upturned hulls of the major vessels of the High Seas fleet were moved to shallower water off Lyness, Scapa Flow. Personal accounts suggest that the salvors would attempt to tow the vessels across the bar at Ryssa Little, sometimes losing superstructure elements in the process. If the upturned hulls did not make it then the salvors would know that the ships were too deep to make it into Rosyth for final scrapping.

One of the aims of this project will be to investigate this assertion and survey the areas around Ryssa Little for these superstructure elements that were lost during these operations.

Recent marine archaeological surveys have collected small amounts of data in regard to the scrap sites indicating that this resource is far more substantial and intriguing than previously believed. The scrap site assemblages include major components of ship structures such as masts, searchlights, plating, steam pinnaces, funnels and so on. Furthermore, these wreck sites, due to their deconstructed nature, are at high-risk of salvage activity.

This project will provide baseline data for long-term monitoring of the sites. The project data and results will be available to the public through the Scapa Flow Wrecks website (http://www.scapaflowwrecks.com), along with various other platforms and exhibitions.

Gairsay Ballast Mounds – Flora and Fauna

Volunteer divers joined a team of archaeologists from the Orkney Research Centre for Archaeology last month to start the second phase of an archaeological project to explore Orkney’s early maritime heritage.

The fieldwork concentrated on Milburn Bay on the small Orcadian island of  Gairsay. The volunteer divers not only discovered ballast mounds but in the clear water also filmed an astonishing array of flora and fauna.

The ballast mounds are colonised by a distinct assemblage of species that sets them apart from the surrounding seabed.  The most obvious constituent is the green alga Codium fragile, which grows abundantly on the mounds and less so in the surrounding area.  Its bright green, branched structure forms a dense canopy that adds to the sheltered habitat already provided among the ballast stones.  Sea squirts are also abundant on the mounds, particularly the large pink species

Its bright green, branched structure forms a dense canopy that adds to the sheltered habitat already provided among the ballast stones.  Sea squirts are also abundant on the mounds, particularly the large pink species Ascidia mentula, distinguished by the white spots around the lip of its inlet siphon. Numerous other species were present around and among the ballast stones, including the sea urchin (Echinus esculentus), green crabs (Carcinus maenus) and a variety of small juvenile fishes.

Exploring Orkney’s Early harbours, Landing Places and Shipping

Volunteer divers will join a team of archaeologists from the Orkney Research Centre for Archaeology in Gairsay on Sunday to start the second phase of an archaeological project to explore Orkney’s early maritime heritage.

The project involves a programme of marine survey fieldwork which will record early maritime sites, structures and artefacts in Orkney.  The recording of material remains, along with the use of historical, place name, ethnographic, cartographic and marine geophysical survey data sources, will help to preserve some of Orkney’s maritime cultural heritage.

This second phase of fieldwork will continue to concentrate on Gairsay, due to the presence of possible ballast mounds or collapsed jetty supports found in Milburn Bay during an earlier phase of the project. Other possible maritime features noted around the edge of the bay will also be investigated over the weekend. The marine archaeologists and volunteers are also hoping to find other maritime features as Milburn Bay has a recorded history of early maritime activity.

It is hoped this project will expand to other areas in Orkney, focusing to begin with on natural harbours with sediments (good for preservation) and involve outreach training, community work and link to other projects.

Being coastal, and in many cases situated directly on the foreshore, maritime sites and structures are most vulnerable to erosion and much information on maritime structures dating before the modern period has probably already been lost to the sea. There is therefore an urgent need for survey and fieldwork that  will help prevent further loss of information.

Thanks to Sula Diving for the video taken for Phase One of the Project.

ORCA staff, Paul Sharman, Senior Projects Manager and Sandra Henry, Marine Archaeologist, will be leading the project.
