The Ulmer Rathaus is a historic municipal building recognized for its ornate, multi-layered exterior frescoes and its iconic astronomical clock. Dating back to 1370, the structure began as a simple department store before evolving into the city hall in 1419. The building features an Early Renaissance facade, added in the 16th century, which showcases elaborate, colorful paintings depicting moralizing biblical and historical scenes. Its most prominent external feature is the large, artistic astronomical clock installed in 1520, which displays zodiac signs and complex timekeeping data. The building suffered significant damage during World War II but underwent extensive restoration to preserve its original artistic character. It currently serves as the seat of the Ulm city administration. Visitors can observe the complex architectural mix of Gothic and Renaissance styles integrated into a single facade.
