Ca’ Rezzonico is a splendid palace by Baldassarre Longhena, a sumptuous Venetian residence hosting a precious collection of 18th century Venetian furnishings and paintings. Of great interest are the palatial rooms and the frescoes by G.B. Tiepolo, J. Guarana, and F. Guardi. On the third floor the Egidio Martini Gallery and its 300 masterpieces. It is a collection of paintings, almost all of the Venetian school, ranging from the 15th century to the beginning of the 20th. It includes works by important masters as well as paintings by artists who owe their place in the history of Venetian art to the studies of Martini himself.
The names represent the very best of Venetian art over a prolific period, which starts well before the 17th century and concludes long afterwards. They include Cima da Conegliano, Alvise Vivarini, Bonifacio de' Pitati, Tintoretto, Palma il Giovane, Bernardo Strozzi, Ippolito Caffi, Emma Ciardi, to name but a few.
 On the third floor of the Museum, you could admire, surprisingly reequipped, The Ai do San Marchi Pharmacy, that was located in Campo San Stin in Venice until 1908.
