Located in the market square of the valuable late Renaissance Tenement House Orsetti, there is a museum presenting the history of Jarosław and the surrounding area. The rich collections include Gothic sculpture of the Madonna and Child, a coffin portrait of one of Jarosław heads, stylized bourgeois interiors, guild and artistic handicrafts, valuable photographs and works of contemporary Jarosław artists. An unusual attraction is the building itself with a large room, basements, an attic decorating the roof and characteristic arcades. Inside you can see a beam ceiling, fragments of the 17th and 18th century polychromies and a Renaissance portal.
Built at the end of the 16th century, the building owes its name to the 17th-century owner, Wilhelm Orsetti of Lucca. He was the initiator of a significant reconstruction, which gave the building a representative character. In the first half of the 18th century it belonged to the sculptor Tomasz Hutter. From 1945 it is the seat of the museum created in 1925.
The institution organizes temporary exhibitions, conducts educational and publishing activities, and has a branch - the Dzieduszycki Museum in Zarzecze.
