Ca' dei Carraresi, Medieval palace in Treviso, Italy

Ca' dei Carraresi is a medieval palace in Treviso, set between the Cagnan river and Via Palestro. Its Via Palestro facade has a five-arch portico on Istrian stone pillars, four trifora windows and a bifora on the first floor, and five small square windows above. The river side has five large arches and a marble basin fed by the Cagnan.

The building appears in documents from the 13th century, but it is unclear whether it was then a private home or already a public inn. In 1354 it was sold as the "osteria alla Croce" by the notary Patresello's family to the Venetian Desenove, who in 1369 resold it to Paolo di Gherardo da Venezia. Between 1396 and 1397 the wooden pillars over the Cagnan were replaced with masonry and a stone terrace was built. The da Carrara family, who ruled Treviso only from 1384 to 1388, probably requisitioned the inn for officials and soldiers; their three coats of arms on the facade were plastered over on 29 November 1388 and brought to light again in the 20th century.

The palace now operates as a cultural venue where art exhibitions and historical collections rotate throughout the year. Its rooms host lectures, performances, and gatherings that connect visitors to the city's contemporary creative life.

The palace can be explored through guided tours available on select days throughout the week, offering access to its interior rooms and layout. It helps to plan ahead since visiting hours may vary with seasons and special exhibitions.

The three coats of arms of the da Carrara family on the facade were plastered over after the Treviso council ordered their removal on 29 November 1388. The covering layer preserved them, and they were brought back to light during the twentieth century.
