Beginning in 2013, the CampusGalli is being built near the town of Meßkirch, South Germany. Within a period of at least 40 years, the Plan of Saint Gall (before 830 A.D.) shall be realised for the first time, with equipment used in the 9th century. During this time, the construction site can be visited by the public. The Campus Galli is a living history museum. The staff will be made up by full-time craftsmen and volunteers as well. The regular employees are trained to hold up high standards in the branches of high-quality replicas, historical knowledge, didactics and presentation techniques. Beside the creation of the 52 building forming the Plan of Saint Gall, this long-term project offers many opportunities for experimental archaeology. Therefore, the Campus Galli invites the scientific community to contribute with their own ideas for new experiments to the project. Thus, the construction site can turn into a place where early medieval culture can be explored, experienced and preserved.
