The university town of Konstanz is the largest on the Bodensee; it straddles the Rhine as it flows out of the lake, placing itself both on the Bodanrück Peninsula and the Switzerland side of the lake, where it adjoins the Swiss town of Kreuzlingen. Konstanz is among the best-preserved medieval towns in Germany; during the war the Allies were unwilling to risk inadvertently bombing neutral Switzerland. On the peninsula
side of the town, east of the main bridge connecting Konstanz's two halves, runs Seestrasse, a stately promenade of neoclassical mansions with views of the Bodensee. The Old Town center is a labyrinth of narrow streets lined with restored half-timber houses and dignified merchant dwellings. This is where you'll find restaurants, hotels, pubs, and much of the nightlife.
It's claimed that Konstanz was founded in the 3rd century by Emperor Constantine Chlorus, father of Constantine the Great. The story is probably untrue, though it's certain there was a Roman garrison here. In the late 6th century Konstanz was made a bishopric; in 1192 it became a Free Imperial City. What put it on the map was the Council of Constance, held between 1414 and 1418 to settle the Great Schism (1378–1417), the rift in the church caused by two separate lines of popes, one ruling from Rome, the other from Avignon. The Council resolved the problem in 1417 by electing Martin V as the true, and only, pope. The church had also agreed to restore the Holy Roman emperor's (Sigismund's) role in electing the pope, but only if Sigismund silenced the rebel theologian Jan Hus, of Bohemia. Even though Sigismund had allowed Hus safe passage to Konstanz for the Council, he won the church's favor by having Hus burned at the stake in July 1415. In a satiric short story, the French author Honoré de Balzac created the character of Imperia, a courtesan of great beauty and cleverness, who raised the blood pressure of both religious and secular VIPs during the council. No one visiting the harbor today can miss the 28-foot statue of Imperia standing out on the breakwater. Dressed in a revealing and alluring style, in her hands she holds two dejected figures: the emperor and the pope. This hallmark of Konstanz, created by Peter Lenk, caused controversy when it was unveiled in April 1993.
Most people enjoy Konstanz for its worldly pleasures—the elegant Altstadt, trips on the lake, walks along the promenade, elegant shops, the restaurants, the views. The heart of the city is the Marktstätte (Marketplace), near the harbor, with the simple bulk of the Konzilgebäude looming behind it. Erected in 1388 as a warehouse, the Konzilgebäude (Council Hall) is now a concert hall. Beside the Konzilgebäude are statues of Jan Hus and native son Count Ferdinand von Zeppelin (1838–1917). The Dominican monastery where Hus was held before his execution is still here, doing duty as a luxurious hotel, the Steigenberger Insel-Hotel.
