The Siena city was important in history as a commercial and banking city until surpassed by Florence in the 13th–14th century. with moral depression following the Black Death and the economic decline, building activity was largely suspended in the 16th century, and because most modern building has taken place outside the city walls, Siena remains essentially a medieval town. With an overall prosperity that enabled them to embellish their city with beautiful churches, palaces, towers, and fountains. Fortunate Siena escape the damage during World War II, so we could still appreciated the beautiful from their golden age. The best of the best must the shell-shape Piazza del Campo with the quadrangular form fountain - Fonte Gaia, and on one side walled with the Palazzo Pubblico, first build in 1297. right beside is the Torre del Mangia. Another Siena's magnificent beauty is the black and white Italian Romanesque cathedral - The Duomo. The wild sculptures on the exterior of the building are stunning! And there are much more Piazza, Palazzo and church to see inside the old city. it is just amazing! navigating up and down, criss-crossing the stone alleys, in some point remind me of the old images of Jerusalem.
