A bog in Schleswig, southern Jutland, which yielded a rich votive deposit of the Roman Iron Age. The main finds were more than 100 iron swords (some with damascened blades, others stamped with the maker's name), and a wooden boat some 21 m long. The boat was clinker-built, had no mast or sail and was provided with 15 rowlocks on each side. The bow and sternpost were upturned, and the vessel was steered by an oar. It is now a famous exhibit, the Nydamboot (Nydam boat). This 4th-century Viking ship was discovered in 1863 in the Nydam marsh. It was one of the most important archaeological finds of the Migration Period. The boat is believed to have been typical of the vessels used by the Anglo-Saxon migrants coming to England in the 5th century. Its construction, however, would have made this a dangerous journey and it is likely that its use was confined to the tideless sea of the Baltic.
