The noble homes of Portogruaro frame the historic centre and embellish its architectural beauty. The most important include the 15th century Palazzo de Götzen, Casa Longo, with its important decorative compositions, Palazzetto Fratto, which also hosted Ippolito Nievo, Palazzo Moro, with two elegant trifora, and Palazzo Muschietti, still embellished today by an external frieze featuring fruit under the eaves of the roof.
