I was lucky to have stayed in Sienna for 1 month in August so I was able to attend the Palio dell'Assunta which is held on August 16, in honour of the Assumption of Mary.
Il Patio does held twice a year at Piazza del Campo one in July and one in August.
10 contrades out of the 17 will enter into the race which last less than 2 minutes. Don't hold your breath, it finished so fast before you realized it started.
The Town Square just filled with this energy before the race, arrive a little early if you want to get a spot.. but trust me, doesn't matter where you are, you cannot really see much...because it is so crowded!!
Personally I enjoyed the pre and the post race celebrations a lot more, just go around the different contrades and of course after the race to the winner for a great celebrations!
Just imagine the first modern II Patio was held 1656.. over 350 years ago.... the tradition even dated back to the Medieval time. read more
