Follow the narrow spiral staircase to the top floor and walk up to the high wall, you can see the mountains in the distance and most of Siena's cityscape. If I weren't a little afraid of heights, I could climb the top wall to see farther, who makes the weather in Italy brighter than China. Leave the opera museum and then there is another attraction on the side of the church called the Siena Baptist Church. It is actually a church chapel. It is probably the place where the church is baptized.
