The Uffizi is the most famous, but Florence also has other amazing museums a short walk away with world class artistic treasures.
 
Galleria degli Uffizi Florence
Galleria degli Uffizi, Piazzale degli Uffizi, ? +39 055 294883, . Tu-Su 8:15AM-6:50PM. Justly one of the world's most famous fine art museums. The collections of Renaissance paintings and sculptures from classical antiquity are superb. Included is The Birth of Venus by Sandro Boticelli. There are often long lines (several hours' wait is common) starting even before the doors open. Useful tip: You can call (+39 055 294883) to make a reservation in advance and walk right in, which is strongly recommended if you can spare the extra ?4. The phone operator will give you an extension number which you quote at Gate 3 to pay (cash only) and get the tickets. Online booking is available but is much less convenient because it costs more, has a 24 hour waiting period, your specified time may change and you need to print an email. The restaurant/caffè has a large balcony overlooking the main piazza with good views of the Palazzo Vecchio. It is a great place to take a break for art lovers making a non-rushed visit to this fantastic collection. This cafe is rather expensive however. Street performers are often seen outside the Uffizi. Admission ?6.50 (Mar 2009) (Phone booking: ?4 extra; Online booking: ?7.25 extra).  edit
