Piazza del Campo, with its unique shell-shaped and slanting design, is
one of Italy's most famous piazze, mostly because of "Il Palio", a horse
race that dates back to the Middle Ages and that still takes place on
the piazza every year.
Palazzo Pubblico (City Hall)
At the top of the piazza, there's a beautiful fountain called Fonte Gaia (Fountain of Happiness).
The fountain's rectangular marble basin was once decorated by panels
carved by Jacopo della Quercia, but these were replaced by slightly
altered copies during the 19th century (the originals can still be seen
at the Santa Maria della Scala museum).
