Immenstaad is a commune and a village in Baden-Wuerttemberg, Germany, on the north shore of Lake Constance.
The first documented reference to Immenstaad dates to the year 1094, when the Bavarian Duke Welf IV acquired the possessions of Weingarten Abbey. The controlling authorities were strongly factionalized until the Fürstenberg family bought the entire town in the late 18th century. In 1806 the town became a border town in the state of Baden-Württemberg.
Immenstaad was the home of the former Dornier aerospace company, which now is part of the EADS-company. It is more famous as a popular resort and well known for its wine and fruit farming activities.
