The octagonal Tribuna is the pearl of the Uffizi symbolizing the four elements. The cupola with shells is the sea, the scarlet silk on the walls is the fire, while the lantern and the wind rose represent the air. The marble floor and the precious table standing in the center, are the earth of course. By the 1770s it was the most famous room in the world.
In the center of the Tribuna you can see the Medici Venus by a classical Greek sculptor. The painting on the walls are portraits of the members of the Medici family.
The grand-ducal collection of the Uffizi comprises thousands of paintings of all times. It is impossible to see all of them in one day. If you try to get the museum visit over in one day, the result is always a dead-tired tourist, who conceives a dislike for the museums forever.
You should be selective, and concentrate only to the art works you are most interested in. I would like to call your attention to one thing only: expect to spend some time in front of the magnificent Doni Tondo in its original frame, the only known preserved panel painting by Michelangelo. Some famous highlights, such as Birth of Venus and Primavera from Botticelli, Tiziano's Venus of Urbino, Leonardo's Annunciation, or Pope Leo X by Rafaello you should not pass by.
At the end of the visit, go up to the terrace bar at the top, and drinking a cool Campari you can admire the fantastic view of Piazza della Signoria.
