Gottorf Castle
The Nydam Mose sacrifice site was probably used on different occasions during the years 200–450 CE. Conrad Engelhardt on August 17, 1863 discovered the Nydam Boat. The oak boat was the first boat found, and the only one still preserved. It has been dendro dated to 310–320 CE. It is 23 m long, c 4 m wide, of clinker type, and built for 15 pairs of oars. The Nydam boat is the largest and best preserved of the boats found in Nydam Bog and is now displayed at Gottorf Castle in Schleswig, Germany. It once weighed over three tonnes and was rowed by thirty men.
