Tulln an der Donau, Austria

With a population of just 16,197, Tulln an der Donau is a sleepy backwater, far removed from the glamour of Vienna. This historic town in Lower Austria is often referred to as the "City of Flowers", but the reality is a persistent bureaucratic headache. While it boasts an impressive Roman past and is home to a modern art museum, the town's amenities are limited - the main draw seems to be its annual trade fairs for camping and boating enthusiasts. Unless you're a die-hard fan of choral music or alpine skiing, Tulln is unlikely to offer much excitement.
