Erdstall

[citation needed] In his 2000 publication Die Regional-Typisierung der Erdställe, Herbert Wimmer created a rough classification system for varying types of erdstall:[2] There is almost no archaeological material to be found in the tunnels, although erdstall tunnels exist in abundance in central Europe, with 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.

[citation needed] The archaeological evidence is so slim that even age determination is difficult.

[citation needed] Most erdstall sites are too narrow to be usable for general tourism.

[3] The Erdstall am Kapellenberg in Großkrut (Lower Austria) was opened in 2007 to visitors of the Erdstallmuseum Althöflein.

Entry to the Ratgöbluckn erdstall at Perg, Austria – its passages are high enough for tourists to access (electric lights since 2002)
