Tartini House, on the north side of Tartini Square, is the building in which the composer Giuseppe Tartini was born in 1692. The medieval lower floors and the eighteenth-century painted ceilings have been carefully preserved; one of his original violins is on display alongside personal documents, portraits, and a small exhibit on the music of his time.
It is a small museum — half an hour does it — and ideally combined with a visit to the cathedral. Concerts are sometimes held in the upstairs hall in summer; check the season programme at the door.
