|Nydam Mose ("Nydam Bog") is a modern day excavation site located at Øster Sottrup, a town located in Sundeved, eight kilometres from Sønderborg, Denmark.|
The bog, which in the Iron Age was a sacred lake, where the weapons and ships of vanquished armies were offered to the indigenous gods in thanks for victory over the fallen enemy. Many items were deliberately destroyed (broken or hacked into pieces) in ritual sacrificial acts, from the period 200 to 400 AD. The particular fascination with Nydam Bog in comparison to other sacrificial bogs is that this archaeological location has played an important – occasionally even dramatic - role in the Danish national fight for Southern Jutland.
The first known finds from the bog date from the 1830s, when a local farmer gave old swords and shields as toys to his children. Amongst numerous other items, three boats were found in Nydam Bog: an oak (egetræsbåden) boat, the Nydam Boat, which is on display at the archaeological museum in Gottorp Castle, Schleswig, Germany. In particular, the 23 metre long oak boat, commonly known as "the Nydam Boat", maintains a distinguished position amongst Danish Iron Age finds, as it is the oldest known rowing vessel in Northern Europe.
