In the Middle Ages (1 000-1 500), the area between the Alps and Lake Constance (Bodensee) developed into an important economic, transit and trade area.

Some cities joined together to form confederations or alliances of cities, introduced a uniform currency system and formed hubs for regional and international trade.

Some 150 artefacts from Austria, Germany, Switzerland and Liechtenstein depict this medieval period of politics, agriculture, crafts, trade and shipping.

The exhibition (Mittelalter am Bodensee. Wirtschaftsraum zwischen Alpen und Rheinfall) shows economic unity in political disunity.
