The Burgberg nature reserve with a size of 41.5 hectares is located south of Oestrich . The castle hill was designated as a nature reserve (NSG) by the Märkischer Kreis in 1997 with the Iserlohn landscape plan. The NSG is divided into a western and an eastern part by the federal highway 236 .

The two rocks Pater and Nun are located in the NSG Burgberg . Prior to the designation of the NSG Burgberg, these were designated as natural monuments for Father and Nun .

Area description

The castle hill is made of lime. On the castle hill are the remains of the ring wall of the Oestrich castle, which was destroyed in the 13th century . The remnants of the ring wall system are designated as a ground monument .

To the east of the NSG Burgberg is the Sonderhorst nature reserve . This nature reserve Sonderhorst is partly only separated from the Burgberg by Schleddestrasse. The Dechenhöhle is only separated from the NSG Burgberg by Schleddestrasse. On both sides of the valley of the Grüner Bach and the Lenne there are further nature reserves on limestone cliffs near the castle hill.

Protection purpose

The determination was made according to the Iserlohn landscape plan to secure the efficiency of the natural balance by preserving rare plant and animal species in a complex biocenosis consisting of semi-arid grassland , pioneer stocking and indigenous hardwood stocking with rich herbaceous layers, to secure the rocks Pater and Nun , to preserve the former quarry as geoscientific Object as well as to protect the early medieval ramparts of the Oestrich Castle from destruction.

Protective measures

According to the landscape plan, arable land should be converted into grassland to restore species-rich communities.
