Siena, like other Tuscan hill towns, was first settled in the time of the Etruscans (c. 900–400 BC) when it was inhabited by a tribe called the Saina.
The medieval Siena Cathedral (Duomo) dates from the 13th century. The exterior and interior are constructed of striking white and greenish-black marble in alternating stripes. And yes, all of the cathedrals started to blur together but I never tired of seeing them! Isn't this Duomo gorgeous?

Siena is famous for its medieval cityscape and has been divided into wards since medieval times. Each ward (contrada) is represented by an animal or mascot and has its own boundary and distinct identity. Ward rivalries are most rampant during the the Palio, an insane horse race held here twice yearly in the Piazza del Campo. (If you're not squimish there are many youtube videos to watch the race but too many horse crashes for my taste!)
