In 2010, an inventory of the „Historischen Natursteinmauern in Innerbraz“ (Historic walls made of natural stones) was created in the course of a research project. The total stock of walls was not known until the finalization of the survey. This is why it would not have been possible to research their origins till then. As the contracting authority, the Department of Spatial Planning of the State of Vorarlberg, has not ordered such profound research, the subject of the wall‘s origins has only been touched in the inventory. This master thesis takes on the survey. The main subject is to develop a chronological classification and dating of the walls. The combination of sources as literature, plans, orthophotos, historical photographs and the buildings themselves should bring a comprehensive view on the walls. Plans and orthophotos of different age, provided by the State of Vorarlberg, were used to find the historic development in the surrounding of the walls. Former land use and the changes within time were used to draw evidence. The examination of plans, orthophotos and historic photographs brought an extensive insight in the development of the landscape surrounding the walls. This led to a classification of the walls into four different categories. Some walls were left unclassified. As next step, a comparison of the structural form of the walls within the categories was made. Walls with similar construction characteristics were put into a sequence. This sequencing and the evidence found in changing landscape structures led in some cases to a further split-up of the categories. The following different age classes could finally be identified: „< 1883“, „1883-1884“, „1880ies-1930ies“, „< 1930“ and „1933“. Three walls had to be left unclassified. Within the different age classes there are subcategories which discriminate between different origins or former functions of the walls.
