Friedrichshafen, a town of Germany, in the state of Baden-Wuerttemberg, on the east shore of the Lake of Constance, at the junction of railways to Bretten and Lindau. It consists of the former imperial town of Buchhorn and the monastery and village of Hofen. The principal building is the palace, formerly the residence of the provosts of Hofen, and later the summer residence of the royal family. To the palace is attached the Evangelical parish church. The town has a hydropathic establishment and is a favourite tourist resort. Here are also the natural history and antiquarian collections of the Lake Constance Association. Buchhorn is mentioned (as Buachihorn or Puchihorn) in documents of 837 and was the seat of a powerful countship. The line of counts died out in 1089, and the place fell first to the Welfs and in 1191 to the Hohenstaufen. In 1275 it was made a free imperial city by King Rudolph I. In 1802 it lost this status and was assigned to Bavaria, and in 1810 to Wurttemberg. The monastery of Hofen was founded in 1050 as a convent of Benedictine nuns, but was changed in 1420 into a provostship of monks. It was suppressed in 1802 and in 1805 came to Wurttemberg. King Frederick I., who caused the harbour to be made, amalgamated Buchhorn and Hofen under the new name of Friedrichshafen.
