6th February
- every year the Oeversee March takes place in remembrance

In February 1864, rearguard fighting took place between the Danish army and the Prussian and Austrian troops at the Sankelmarker See. There were been many fallen and wounded on both sides. Three monuments were built in their memory. The historical tavern in Oeversee was used as a military hospital at that time. The inn looks like a museum, with pictures, weapons and helmets as striking relics of past events.


The megalithic chambered tomb is 70 m long - it dates from the Neolithic Period (ca. 3500 BC) and has been fully rebuilt.

In the Arnkielpark, you can walk on historical paths through the largest reconstructed megalithic chambered tomb in Northern Europe. Seven stone tombs are waiting to be explored. The archaeological regional park gives lots of exciting impressions from the past and present on numerous multilingual information panels in a spacious info-pavilion.


From the 12th century
- both churches were at that time already on important long distance paths/pilgrimage routes

Find repose, peace and sanctuary – the old St. George Church in Oeversee once acted as a fortress church. On the tower, you can still see the arrow slits. But the altar and the vault paintings are also worth seeing. The St. Peter Church in Sieverstedt, built around 1100 in the Roman architectural style using boulders, is one of the oldest churches in the peninsula of Angeln. There is a lot to discover in this church.
