6 Best Sights in The Bodensee, Germany

This huge castle in the tiny inland village of Salem, 10 km (6 miles) north of Überlingen, began its existence as a convent and large church. After many architectural permutations, it was transformed into a palace for the Baden princes, though traces of its religious past can still be seen. You can view the royally furnished rooms of the abbots and princes, a library, stables, and the church. The castle also houses an interesting array of museums, workshops, and activities, including a museum of firefighting, a potter, a musical instrument builder, a goldsmith shop, a glassblowing shop, pony farms, a golf driving range, and a fantasy garden for children. There is a great path that leads from the southwestern part of the grounds through woods and meadows to the pilgrimage church of Birnau. The route was created by the monks centuries ago and is still called the Prälatenweg (path of the prelates) today. It's an 8-km (5-mile) walk (no cars permitted).

Majestically guarding the town is the original “Meersburg” (Sea Castle). It's Germany's oldest inhabited castle, founded in 628 by Dagobert, king of the Franks. The massive central tower, with walls 10 feet thick, is named after him. The bishops of Konstanz used it as a summer residence until 1526, at which point they moved in permanently. They remained until the mid-18th century when they built themselves what they felt to be a more suitable residence—the baroque Neues Schloss. Plans to tear down the Burg Meersburg in the early 19th century were shelved when it was taken over by Baron Joseph von Lassberg, a man much intrigued by the castle's medieval romance. He turned it into a home for like-minded poets and artists, among them the Grimm brothers and his sister-in-law, the poet Annette von Droste-Hülshoff (1797–1848). The Burg Meersburg is still private property, but much of it can be visited, including the richly furnished rooms where Droste-Hülshoff lived and the chamber where she died, as well as the imposing knights' hall, the minstrels' gallery, and the sinister dungeons. The castle museum contains a fascinating collection of weapons and armor, including a rare set of medieval jousting equipment.

The spacious and elegant "New Castle" is directly across from its predecessor. Designed by Christoph Gessinger at the beginning of the 18th century, it took nearly 50 years to complete. The grand double staircase, with its intricate grillwork and heroic statues, was the work of Balthasar Neumann. The interior's other standout is the glittering Spiegelsaal (Hall of Mirrors).

A short walk from town along the lakeside promenade is this small palace that served as the summer residence of Württemberg kings until 1918. The palace was formerly a priory—its foundations date from the 11th century. Today it is the private home of Duke Friedrich von Württemberg and isn't open to the public. You can visit the adjoining priory church, a splendid example of regional baroque architecture. The swirling white stucco of the interior was executed by the Schmuzer family from Wessobrunn whose master craftsman, Franz Schmuzer, also created the priory church's magnificent marble altar.

Twelve km (7½ miles) west of Lindau (about midway between Lindau and Friedrichshafen) is the small, pretty town of Langenargen, famous for the region's most unusual castle, Schloss Montfort. Named for the original owners, the counts of Montfort-Werdenberg, this structure was a conventional medieval fortification until the 19th century, when it was rebuilt in pseudo-Moorish style by its new owner, King Wilhelm I of Württemberg. If you can, see it from a passenger ship on the lake; the castle is especially memorable in the early morning or late afternoon. The castle houses a restaurant, open for dinner from Tuesday to Sunday, April through October, and on weekends during the colder months. The restaurant is also open for Sunday brunch year-round (10–2, all-you-can-eat German buffet-style brunch). A wine bar features in the atmospheric cellar, open Friday nights. You can also climb the wooden spiral staircase to the top of the tower for views across the lake to Switzerland, Austria, and over the rolling German countryside.

Six kilometers (4 miles) west of Lindau lies Wasserburg, whose name means "water castle," a description of what this enchanting island town once was—a fortress. It was built by the St. Gallen monastery in 924, and the owners, the counts of Montfort zu Tettnang, sold it to the Fugger family of Augsburg. The Fuggers couldn't afford to maintain the drawbridge that connected the castle with the shore and instead built a causeway. In the 18th century, the castle passed into the hands of the Hapsburgs, and in 1805 the Bavarian government took it over. Wasserburg has some of the most photographed sights of the Bodensee: the yellow, stair-gabled presbytery; the fishermen's St. Georg Kirche, with its onion dome; and the little Malhaus museum, with the castle, Schloss Wasserburg (now a luxury hotel), in the background.
