Sonthofen is the most southerly town of Germany, located in the Oberallgäu region of the Bavarian Alps. Neighbouring Oberstdorf is situated 14 km farther south but is not classified as a town. In 2005, Sonthofen was awarded "Alpenstadt des Jahres" (Alpine city of the year). The town has 21,300 inhabitants (as of 31 December 2015).
Findings show that the Sonthofen area was already inhabited from the Stone Age to the Roman Empire. In the 6th/7th century Germanic Alamans settled n the area at the foot of the Kalvarienberg. On the top of the hill, one suspects an old Thing site.
Sonthofen was first mentioned in a document in 1145. It had held the market right with important proprietary rights since 1429.
In 1803 Sonthofen came to Bavaria. In 1804 Sonthof Castle becomes the seat of a Bavarian Landgericht (regional court) responsible for justice and administration.
In 1963 the previous market town of Sonthofen is given the town charter. In 1972 Sonthofen becomes the county seat of the newly formed district of Oberallgäu.
In World War II Sonthofen was bombed twice because Adolf Hitler had built the Ordensburg Sonthofen where young boys were trained for service in Nazi Party organizations. The "Ordensburg" was not destroyed in the war. From 1946 to 1948 it was home to the United States Constabulary school, from May 1951 through February 1952, was used by the United States Air Force in Europe as a basic training center, and from 1956-2009 the German Bundeswehr located its Military Police (Feldjäger) and Staff Service School there. The German Army's NBC Defence School (ABC-Abwehr- und Selbstschutzschule) is located in another barracks in Sonthofen.
