Archaeology There is almost no archaeological material to be found in the tunnels  although erdstall tunnels exist in abundance in Central Europe ( over 700 in Bavaria alone ) . This makes it highly unlikely that they were ever used as dwellings, such as a hiding place in times of war. The archaeological evidence is so slim that even age determination is difficult. Coal from a fire pit at Bad Zell has been dated between 1030 and 1210. Coal from a heading in Höcherlmühle has been dated between the late 10th and mid-11th century. A slip passage at Rot am See has been enhanced with stones to make it narrower with the stone additions dated to between 1034 and 1268. Coal from Trebersdorf was dated 950 to 1050, coal from Kühlried was dated to 950 to 1160. Ceramics found in St. Agatha have been dated to the 12th century  which seems to be the latest date of usage.
