It is located in the old town hall and stores documents from over 700 years of civic and regional history.

In 1472 the burgermeister Konrad Lerhueber instituted the so called Stadtbuch as the towns official register of legal acts.

As in 1907 the municipality moved to Bolzano's new town hall, the historic documents were transferred to the Civic Museum and recorded by the Austrian historian and archivist Karl Klaar who made an inventory still valid today.

Among the many documents preserved, of peculiar interest to the historic sciences are the archives of the former Hospital to the Holy Spirit (Heilig-Geist-Spital) existing from the late 13th to the 19th centuries.

[5] There is also preserved an excerpt of the Middle High German Christherre-Chronik in a copy dating back to 14th century.
