Siena has a fair few churches and they're all beautiful in their own way.
This one isn't as ornate from outside as some of the other churches but still beautiful and worth a visit. We didn't go inside but if you have time it maybe worth a potter around.
This Roman Catholic church dates back to the 11th - 12th century, making it one of the oldest in Siena. It sustained damage during an earthquake in 1798. Renovations were done in the 1920's. It is a small church but worth stopping in for a visit.
