Uhldingen-Mühlhofen is a town at the northern shore of Lake Constance, Germany between Überlingen and Meersburg. The town is a popular holiday destination and home to the Pfahlbauten open air museum in Unteruhldingen and the cathedral of Birnau.
The town consists of the three villages Unteruhldingen, Oberuhldingen und Mühlhofen. Further, the hamlets of Seefelden, Maurach, Obermaurach, Gebhardsweiler and Hallendorf are included in the area of the commune.
Archeological finds show that the shore of Lake Constance near Unteruhldingen was already inhabited during the Neolithic and Bronze ages. During the time of the Roman Empire there may have been a port, as the discovery of coins from the 1st century AD suggests. Oberuhldingen is situated at a Roman road from Meersburg to the valley of Salem (Baden) where remains of a Roman estate have been found.
