The region of Tuscany encompasses big cities like Florence and Pisa, as well as Siena and Livorno. Archicture buffs won't know just where to start when it comes to exploring the architectural attractions in these cities.

Florence alone is a stunning example of a city chock full of architectural gems. When you're there, you can't miss out on places like the Duomo (otherwise known as the Cathedral of Santa Maria dei Fiori) or the Ponte Vecchio bridge - it's the most ancient bridge in Florence and many a photographer has stopped to snap a shot of the iconic structure. San Marco, Giotto's Bell Tower, Pitti Palace - the list goes on and on. Of course there are many churches to explore and admire, as one might expect in Italy. All have their own story and history and no trip to Tuscany would be complete without a stop in Florence to gaze upon some of these buildings and structures that have been standing for generations.

Of course, in Pisa, you have the architectural wonder known as the Tower of Pisa. Built in 1173 (well, begun in 1173), the tower leans because it was built on unstable soil - the thing had begun to tilt (due to the south side sinking) even before workers had completed the third level. Renovations in the past decade have tried to correct the tilt or at least keep it from becoming worse. As of 1990, the tower was tilting over 13 feet over - now it's leaning about 20 or so inches. Only 30 people are allowed in at a time. While it may be a bit overrated, it's still a fascinating structure. Additionally, the Duomo cathedral is another building to check out located in the Piazza del Duomo along with the Leaning Tower and Camposanto cemetary.

In Siena, you'll find yet another "Duomo" - the Siena Cathdral, as well as the Mangia Tower, Cappella di Piazza and Santa Maria dei Servi, just to name a few.
