FRIEDRICHSHAFEN, a town of Germany, in the Land of Wurttemberg, on the east shore of Lake Constance, at the junction of railways to Bretten and Lindau. Pop. 306. It consists of the former imperial town of Buchhorn and the monastery and village of Hofen. Buchhorn is mentioned (as Buachihorn or Puchihorn) in documents of 837 and in the 12th century passed through the hands of the Welfs to the Hohen staufen. In 1275 it was made a free imperial city by King Rudolph I. In 1802 it 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, was suppressed in 1802, and in 1805 came to Wurttemberg. King Frederick I., who caused the har bour to be made, amalgamated Buchhorn and Hofen under the new name of Friedrichshafen. The principal building is the palace, formerly the residence of the provosts of Hofen, and here are also the natural history and antiquarian collections of the Lake Constance Association. Zeppelins are built here and in 1924 the L.Z. 126 flew from here to America and back. Its other industries include motor cars and tanning.
