Palazzo Tolomei stands in Via Banchi di Sopra and dominates a little square called Piazza Tolomei in whose center there is pillar bearing the  symbol of Siena, a metal she-wolf suckling human twins, which dates back to 1610. Palazzo Tolomei dates back to the 13th century, it is made of stone and has two orders of  beautiful rectangular double windows surmounted by pointed arches. 

Also in the piazza is the Church of San Cristoforo. Originally Romanesque, it was completely remodeled in the 18th century after being damaged by an earthquake. The church has an impressive wooden crucifix and a marble-sculptured high altar.
