stepping stones of maritime history

History

The wreck was investigated in summer 2001 by the State Archaeology Department of Schleswig-Holstein in cooperation with the Arbeitsgruppe für Maritime und Limnische Archäologie (work-group for maritime and limnic archaeology) at the University of Kiel and the Maritime Archaeology Research Centre at the Danish National Museum in Roskilde.

The wreck was acutely threatened by marine borers and erosion, so a recovery and preservation was undertaken. The ship-timbers were recovered by divers at a depth of only 1.2-1.5 metres with nearly no visibility.

Description

The wreck features constructional details diagnostic for the Nordic clinker building tradition, i.e. radially cleft clinker planks of oak fastened together with iron rivets, mouldings along the plank edges, as well as the biti-system.

The wreck was repaired with a sintel-caulking (i.e. caulking cramps), which is untypical for the tradition it was built in. Several isolated sintel-finds have been also made in Schleswig for the first half of the 13th century, indicating that the sintel-technology has apparently crossed the land-bridge from Hollingsted to Schleswig, arguably by visiting tradesmen from the North Sea region – e.g. Frisia, Westphalia or Saxony – where the sintel-technology originated.

The dendrochronological analysis has revealed that the wreck was built in the 1140's with timber from the island of Fyn, Denmark.

Although the keel is only preserved up to a length of almost 8 metres, the reconstruction based on the individual timbers indicates a much larger vessel of ca. 25 metres in length. As such, it is one of the largest cargo vessels of the High Middle Ages.

A multitude of smaller finds associated with the cargo were made during the underwater excavation, which prompted hypotheses on the vessel's route. For instance, 300 wooden pins were interpreted as fur-pins in the context of trade relations of Schleswig's St. Canute Guild with Russian fur traders.

Length82 feet (25 m)
Width21.7 feet (6.6 m)

Status

The ship-timbers were conserved with PEG in the State Archaeology Museum of Schleswig-Holstein at Gottorf Castle.
