About the museum
In June 1990, the state government of Baden-Württemberg decided to found a state archaeological museum. Because suitable premises were lacking in Stuttgart, work began in the vacant convent building of the former Benedictine abbey of Petershausen in Konstanz – initially only as a branch of a planned main museum in the state capital, which, however, was never realized. During the conversion of the building, erected in 1767, the Baroque layout with long corridors and monastic cells was largely preserved; some cells were combined into exhibition rooms. The display collection opened in March 1992. The founding director was state archaeologist Dieter Planck.
Later, a striking annex was added whose facade traces the outline of its most important exhibit: a cargo ship about 18 meters long from the 14th century, discovered in Lake Constance off Immenstaad in 1981. Since 1999, the museum has also included the Zentrales Fundarchiv (central finds archive) in Rastatt, which houses excavation finds from the entire state. Since 2003, the ALM has also managed several branch museums – today seven sites across the state, including the Limesmuseum Aalen, the Federseemuseum, and the Museum für Urgeschichte in Blaubeuren. Since 2012, the ALM has been a state-owned enterprise.
Spread over three floors, the Konstanz display collection spans the Stone Age to the early modern period. Its focal points are the pile dwellings, part of a UNESCO World Heritage Site, with exceptionally well-preserved wood and textile finds; the Roman and medieval history of Konstanz; the early Middle Ages; and navigation on Lake Constance. For several years, the permanent exhibition has been gradually redesigned; modernized rooms are to be completed by 2035, with a new Celtic gallery planned for the end of 2028.
