Haus Keppelborg in Heek is a former Burgmannshof of the Landesburg Nienborg whose history probably dates back to the 15th or 16th century. This historic building opened its magnificent doors on 2 February 2023 and brought the medieval splendour of the former Landesburg Nienborg to life. Guests at this event brought their own picnic and enjoyed a literary evening with tales of Münsterland luck as well as musical accompaniment in the form of mystical ballad singing in front of the open fire. A "Münsterland Winter Punch" from the Münsterland Seal was also served at each fireside picnic.
