When you approach the small town of Meersburg by boat, you can see it directly: the magnificent red building Gredhaus, which lies directly on the shore. The house was first mentioned in a document in 1498 when Hugo von Hohenlandenberg, the Bishop of Constance, sold it to the town of Meersburg. Since then, the Gredhaus has served as a covered trading place and warehouse. It was mainly grain that was traded with the Swiss partners on the other side of Lake Constance. The name of the house goes back to the step-like galleries, in Latin “Gradus”, on which the goods were offered. In 1899, the Gredhaus was extensively modernised.
