The D Ring master plan is for the development of an Event and Racing complex in Horstel in northwestern Germany. The initial phase of this project was planned for 2011 to 2012, where necessary maintenance and renovation of the existing conditions was completed. The building phase is expected to be completed by 2015. The vision involves the creation of a new dynamic space, which caters to families and people of all ages. The many zones of the master plan will hold spaces for events and festivals of various scales, suitable for a range of outdoor and indoor activities. A 1.5 km race track is going to be created in and around the Munmont building, where the building itself will be transformed into a hotel, restaurant and workshop. The former tower and its surrounding buildings are reused as a race control centre, pit and paddock boulevard. With minimal adaption to the space, large events such as dance or music performances can be hosted in the existing hangars, which can also be used as film studios. The shelters will be restored and converted into restaurants, car showrooms, museums, etc.
