This little church, just opposite the Palazzo Tolomei, is worth just a brief glance if it is open. It is among the oldest in Siena and in the Middle Ages housed one of the governing councils of the city. It was renovated in the 18th and 19th centuries and is now a simple but elegant neo-classical building with a mainly baroque interior.At the alter end of the right wall, there is a spirited painting of St George and the Dragon – the latter has cleverly coiled his tail round one of the saint’s horse’s legs. There is much argument among art historians as to the artist.Above the main alter there is dramatic marble sculpture of the transit to heaven of St Benedict, helped on his way by two angels, in high baroque style By Giovanni Antonio Mazzuoli (1693).
