Polo (or Paolo) Zulian, already a renowned figure in Venice due to several ambassadorships, was elected Duke of Candia in 1382, but declined out of modesty.

They probably built the palace over a pre-existing building owned by them, as the family is registered in the estimo of the Contrada of Santa Fosca since 1379.
