Palazzo Marcello is a Venetian building located in the Cannaregio district and overlooking the Grand Canal between Palazzo Vendramin Calergi and Palazzo Molin Erizzo.
In the mid-fifteenth century the building belonged to the Molin della Maddalena family and at the time consisted of only one floor, in addition to the mezzanine and ground floor. It passed to the Marcellos in 1517 due to the marriage between Marco Antonio Marcello and Caterina Molin di Nadalin. It was rebuilt on older structures towards the end of the 17th century. In this palace, the sea captain Lorenzo Marcello was born in 1603 and the composer Benedetto Marcello in 1686. In this building where he lived, the English writer Frederick Rolfe died of a heart attack on 25 October 1913.
At noble floor level, the building has two large five-light windows made up of windows decorated with round arches. The building has the traditional tripartition. The presence of two water portals suggests a two-family use of the residence.
