What could be the cutest building in Ulm is the Schiefes Haus, a rickety inn from the start of the 15th century.This corbelled, half-timbered house was used by Ulm’s shipmasters for hundreds of years.At an incline of between 9 and 10° the Schiefes Haus looks like it’s just about to collapse, but is still going strong 600 years after it was built.Adjustments have had to made over time, especially after the side facing the river started sinking in the 1600s.According to the Guinness Book or Records it’s the most crooked hotel in the world (literally, not figuratively!). If you’d like to book a room you can rest easy knowing that your bed will at least be flat; the furniture adapts to the slope, which can be as much 40 cm in each room.
