If the poet is truly buried here, then it's in a very beautiful setting, fitting for him, with magnificent heathland. It's generally easy to get here by bike, as long as you don't expect a paved path; otherwise, you can push your bike a bit. This heathland isn't that big.

The monument in honor of Hermann Löns is located in a small but very beautiful heathland. A few meters away is also Hermann Löns's grave.

At the site of the former "Hansa" oil field near Hademstorf in the Allermarsch region, approximately 160,000 tons of crude oil were produced between 1941 and 1970. Today, two restored horsehead pumps, installed on the foundations of the "Hansa 6" and "Hansa 9" production sites, commemorate this technical history. The pumps were used to bring oil to the surface from depths of up to 1,350 meters. Together with the historic oil bridge, they represent significant evidence of the regional oil boom—well-documented by the Aller-Leine Valley Navigator and open to the public as a technical monument.

The war memorial in Bothmer was erected around 1920 as an obelisk-shaped monument made of fieldstone. Set within a landscaped and fenced area, it commemorates the fallen of the First World War with reliefs of an iron cross and a helmet decorated with oak leaves, whose names are inscribed on a granite slab. After the Second World War, a second plaque was added for the fallen and missing from 1939 to 1945. Today, the memorial enjoys protection as a historically significant individual monument.

The Cordingen Mill is a former watermill with a mill yard (miller's house and bakehouse) and ponds, located in the Warnau Valley between Cordingen and Benefeld (part of the town of Walsrode) in the southwestern Lüneburg Heath. The mill was first documented in 1661. Restored in the 1980s by the municipality of Bomlitz, the complex is considered one of the most valuable historical buildings in the Heidekreis district. The mill, built in 1810, operated until the 1950s. Today, the mill building is used for civil weddings by the town of Walsrode and is also available for private events. The miller's house contains an exhibition of documents and manuscripts about and by Arno Schmidt. The writer lived with his wife on the then fully operational mill yard from 1945 to 1950. His first post-war stories, Enthymesis, Gadir, Leviathan, and Brand's Heath, were written here. The Lower Saxony Mill Route passes by the Cording Mill. The rustic-looking mill grounds are very scenic due to their location in the narrowest section of the Warnau Valley, which is almost 20 meters below the surface. It is also one of the starting points for the Eibia-Lohheide recreation area via the Arno Schmidt Trail. Following the steep bank of the Warnau, you can also reach the Bomlitz Archaeological Trail from here. https://de.wikipedia.org/wiki/Cordinger_M%C3%BChle
