The architectural history in Florian is fascinating. At the beginning of its history, the Caffé had no windows and consisted of two rooms furnished with extreme simplicity. In the mid-1700s, probably driven by competition, the Florian expanded with two rooms. Towards the end of the century, the management passed to Valentino Francesconi, nephew of Floriano and then to his son Antonio. After about thirty years, it was bought by the new owners: Vincenzo Porta, Giovanni Pardelli and Pietro Baccanello. It was these new managers in 1858 that entrusted the architect Lodovico Cadorin of the Academy of Fine Arts with the complete renovation of the place with the addition of two rooms, thus giving it the appearance that has remained unchanged until today with its prestigious rooms. Two new halls have been added to the Cafe and all rooms have been given new names. Since then, Florian has kept its prestigious ambience and atmosphere unchanged. The cafe has rooms such as the Freedom Room, the Senate Room, the Chinese Room, the Oriental Room, and the Seasons Room. Each room has its feature. While the Senate Room is important as it is the birthplace of the famous Venice Biennale concept, there are elegant, feminine figures emphasising the beauty and representing the four seasons in the Seasons Hall. The Freedom Room was created in 1920 to celebrate the 200th anniversary of the cafe, and the Art Nouveau movement influenced the architecture of this section. The Chinese Room has elegant and curvy forms on its walls and has a distinct atmosphere like the Oriental Room. Both rooms fascinate their visitors with their unique atmosphere.

The decoration of the “Chinese” room and the “Senate” room was entrusted to the painter Giacomo Casa who depicted “the Enlightened Century, or Progress and Civilization teaching the Nations”, following the very optimistic atmosphere towards scientific progress of this era, a room that is characterised by a Masonic rebus. Then the “Orientale” room, painted by Antonio Pascuti, so named for the oriental motifs. One of the side rooms became known as the “Hall of Illustrious Men”, decorated by Giulio Carlini with oil portraits of famous Venetians: Carlo Goldoni, Francesco Morosini, Titian, Marco Polo, Paolo Sarpi, Vettor Pisani, Pietro Orseolo, Andrea Palladio, Benedetto Marcello and Enrico Dandolo. This Hall has recently been restored, completing the overall restoration of the venue, which began thirty years ago. The “Hall of the Seasons”, or “Hall of Mirrors”, was decorated by Cesare Rota to represent the four seasons with figures of women. The latest acquisition was the “Sala Liberty” from the early twentieth century, characterised by a large vaulted ceiling, wooden floors and original hand-painted mirrors.
