Die Burg, Nature reserve in Marl and Recklinghausen, Germany

Die Burg is a 146-hectare nature reserve shared by Marl and Recklinghausen, split by the Lipperandstraße into a northern section of 99 hectares and a southern section of 47 hectares. Old acid oak woods of sessile oak cover 62.41 hectares, with alder-ash floodplain forests and woodrush-beech woodland beside the Silvertbach and its tributaries. Inside the part left of the stream lies the Sinsener Wallburg circular rampart, recorded as a Bodendenkmal.

The forest appears at roughly its present extent on very old maps. The 1845 district map labels it "Borg", and the Silvertbach was then called Großer Bach. From the Prussian survey of 1894 the maps read "Burg", and by 1921 "Die Burg". The area became a nature reserve in 1983 under key number RE-011.

The name comes from the forest itself: the 1845 district map labels it "Borg", and maps from 1894 onward use "Burg". The Sinsener Wallburg ringwork inside the reserve is recorded as a Bodendenkmal, a protected archaeological monument, rather than a rebuilt fortification.

The area is accessible by walking paths that provide access to different sections of the reserve. Visitors should be aware that certain zones are restricted to protect wildlife and should be approached respectfully.

The forest is already drawn in roughly its present extent on very old maps: the 1845 district map labels it "Borg", and the Silvertbach was then called Großer Bach. The name "Burg" appears on survey sheets from 1894 and is documented as "Die Burg" from 1921.
