Waaghaus, Medieval cultural monument in Bolzano, Italy.

The Waaghaus is a medieval market building in Bolzano's old town, marked by thick stone walls and exposed wooden beams. Its structure displays typical Tyrolean features with compact proportions and practical details from its trading purpose.

The building was built in medieval times and served the city as an official weighing house where merchants inspected goods and paid duties. This function made it a key point in Bolzano's trade network during the Middle Ages.

The name Waaghaus comes from the public weigh-house that operated here until 1780, when grain and liquids were measured under the market statutes. A fresco by Albert and Rudolf Stolz on the connecting arch shows the old scales, and under the arcades a Crucifixion by Silvester Müller survives from the early 16th century. Since 2020 the building has housed the Waag cultural meeting point and the Bolzano offices of the Euregio Tyrol–South Tyrol–Trentino.

The building stands centrally in the old town and can be viewed from outside, allowing you to see the medieval architecture and details without admission. The location is easy to reach on foot and offers photo opportunities from various angles.

The fresco on the arch linking the Waaghaus to the neighbouring arcade house, painted by Albert and Rudolf Stolz in the early 20th century, shows the public weighing scale in a historicising style. Under the arcades opposite, a Crucifixion fresco by Silvester Müller from the early 16th century survives.
