The salvage operation for Skuldelev ships began in 1957 and concluded in 1962. Divers from the Danish National Museum recovered five scuttled Viking ships resting on the muddy bottom of Peberrenden.
Skuldeval 2 is an oak-built warship that dates to approximately 1042 and originated from the Dublin area. Dendrochronology confirmed this specific timeline for the vessel constructed near Dublin.
Five vessels were deliberately scuttled to create a blockship barrier against potential sea-based attacks during the 11th century. This defensive measure targeted the most important channel called Peberrenden near the harbor of Skuldelev to protect local settlements from hostile forces.
A €1.34 million replication project ran from August 2000 to September 2004 to recreate Skuldelev 2. Almost 40,000 hours of labor went into building the replica known as Havhingsten fra Glendalough.
The reconstructed Sea Stallion reached Roskilde once more on the 9th of August completing the round trip. The vessel arrived in Dublin on the 14th of August 2007 and remained on exhibit until the summer of 2008 before returning home.
