The fortress city that survived a miraculous 1634 siege

In short: In the mid-17th century, Swedish forces breached the walls of Überlingen but failed to seize it. The town's desperate house-to-house resistance became so legendary that locals attributed their survival to divine intervention—a belief that persists in a unique annual procession today.

Überlingen’s strategic importance is rooted in antiquity. While Stone Age settlements of the Hallstatt culture thrived along its shores, the Romans later utilized the region as a military corridor between the Alps and the Danube. The city eventually became a primary seat for Alemannic dukes, maintaining a position of power that shaped European lineage; notably, the first wife of Charlemagne hailed from a neighboring family in the same region.

The city's prosperity peaked between the 13th and 16th centuries as a hub for trade and viticulture. Its south-facing slopes produced profitable grapes, funding the construction of the St Nikolaus Munster and significant fortifications. By 1547, Emperor Charles V granted it market rights that prohibited grain or salt trade within a 15-kilometer radius, cementing its status as an economic powerhouse.

Military history defined the city's character during the Thirty Years' War. In 1632 and 1634, Swedish troops besieged the town. Despite a breach in May 1634, the population engaged in grueling street-to-street fighting until the invaders retreated. This 'miraculous' defense inspired the annual Sweden Procession. The city also earned its right to display the Habsburg hawk and imperial eagle for helping suppress the German Peasants' War in 1525.

Following a loss of autonomy in 1803, Überlingen entered a century of economic decline, worsened by the 1815 'Year without Summer.' It was only later 'rediscovered' through its mineral springs. These waters attracted luminaries like poet Ludwig Uhland, whose favorite walk along the western wall remains a public pathway today.
