The Häringmill, located in Wilfersdorf is listed as a historic monument and is considered one of the most beautiful renaissane mills of the Weinviertel, with her history dating back to the 14th century. For a long time it was in the possession of the Liechtenstein royal family and operated until 1958 as a grain mill. The aim of this thesis is, in addition to the historical analysis, to document and analyze the existing inventory in order to finally find a new and appropriate use. The mill can only be preserved in its original state and prevented from any further deterioration if a permanent use for it is found. Nowadays the machine equipment is no longer existent, but nevertheless it is important to understand how the building functioned as an active mill. The first part of this thesis, explores the history and functionality of mills in general.^ ^The following section will revolve around the former mills at the zaya, which will influence the concept for the future utilization of the Häringmill. The next part ist dedicated to Wilfersdorf, where the Häringmil is located. In this section the history of the city, as well as the history of the Liechtenstein family and the Wilfersdorf castle are investigated. However, the primary interest of this thesis is about the Häringmill itself. Beside a short historical overview and the building history, a survey of the Häringmill was untertaken and a room book was created, which are funda- mental for the preservation concept of the mill. One concept for the future purpose of the building is to transform the mill into a museum. The exhibition about the mills of the Zaya is currently located in a local museum in Wilfersdorf. The concept for the future use of the Häringmill could be, to relocate the exhibition to the mill, giving the building a permanent purpose.^ In addition to that the redevelopment concept could include a snack-bar. There is a nearby cycle path and the new snack-bar could provide the cyclist with a convenient location to stop for food and drink as well als exploring the museum whilst they are there.
