Palazzo Duodo is a Gothic-style palace on the Canal Grande, located between the Ca' Tron and the Palazzo Priuli Bon, in the sestiere of Santa Croce, in Venice, Italy. There is a second Palazzo Duodo a Campo Sant'Angelo. The palace was built in the 15th century. In 1712 it was let to Marchese Orazio Lancilotti, and in 1740 there were several tenants. In 1808 it belonged to Carlo Duodo of S. Maria Zobenigo.

Ca' Tron is a palace in Venice, northern Italy, facing the Canal Grande. Part of the sestiere (quarter) of Santa Croce, it is situated between the Palazzo Belloni Battagia and Palazzo Duodo, near the church of San Stae. It is owned by the University Iuav of Venice and houses the Faculty of Territorial Planning. The palace was rebuilt in the late 16th century, under the design of an unknown architect influenced by Jacopo Sansovino as the residence of the Tron family, who lived here until their extinction in the 19th century. The Tron had lived in this parish by the time of the start of the Patriciate. The family produced on Doge, Niccolo Tron in 1471, and nearly a half dozen procurators, and many other Venetian statesmen and generals. Maximilian, Elector of Bavaria, stayed here in 1684; and in 1775 Andrea Tron entertained the Emperor Joseph II with a magnificent ball. Senator Francesco Tron, grandson of Andrea, died here in 1793. In the 19th century the palace nearly fell into ruin. It has been owned by the IUAV since 1972. The building is an L-shaped plan, with a ground floor, a mezzanine and two piani nobili. The latter, differently from the others, have a façade in Istrian stone. The left side of the façade is shorter, and thus the portal and the central openings of the floors are asymmetrically placed. The floors have eight windows, the four central ones joined to form a quadruple mullioned window. The small rear façade, which faces a small garden with a well at the center, features two quintuple mullioned windows with parapets in correspondence of the piani nobili, while at the ground floor there is a single opening divided by two columns. The interior has somewhat dilapidated frescoes by Louis Dorigny, a Diana and Endymion by Jacopo Guarana, and stucco decorations.
