The Lembecksburg is an impressive ring wall from the 9th/10th century. Century and namesake for the island village “Borigsem”, as the “settlement near the castle” is called in Frisian. With a circumference of around 450 meters and a height of up to 13 meters, the ring wall northwest of Borgsum once served as a refuge and protective castle from the Vikings. In the 14th century it came into the possession of the Holstein nobleman Klaus Lembeck. The Danish King Waldemar IV besieged Borgsum Castle in 1374 because Lembeck refused to swear allegiance to him. When the nobleman no longer saw a way out, he sank the treasures into the well and fled in a boat across the tidal creek, which at that time still connected the Borgsum Marsh with the North Sea. The Lembecksburg is now an archaeological monument. On the Lembecksburg grounds you can have a wonderful picnic in the countryside. https://www.foehr.de/ausflugstipps

If you want to ride a bike from Rantum to Hörnum, I recommend NOT taking the paved bike path next to the road, but taking the unpaved bike path further to the left of the road, which is very good to ride in dry weather. There is also a shelter along the way in case there is a storm!

During the excavations carried out in the interior of the castle in 1951/52, the ground plans of the house were uncovered and numerous potsherds, loom weights, iron implements and soapstone vessels were recovered.

On the beach under the Goting cliff there are many boulders from the Saale Ice Age that are over 200,000 years old.

Great landscape, a bike path developed as a gravel path runs parallel to Hörnumer Rantumer Strasse in several curves towards the Watt side. It is good and can also be used by non-mountain bikers without special skills. Great view of the Watt, the Ratum salt marshes, dune landscape.
