Church of San Domenico
Located in the northwest corner of the town, the Church of San Domenico is a welcome break from overly-ornate Italian churches elsewhere ( no names!)
The exterior is simple Tuscan stone, with an unusual and highly attractive slanted bell-tower. The inside is no less refreshing: cool, simple, and an excellent place for contemplation.
The square outside of the church of the same name is also a pleasant expanse of public space, but was pretty empty when I visited. However, it was very peaceful and pleasant, and punctuated by squeals of children at a nearby school or daycare center.
