The one dedicated to St. Peter the Apostle is the main church in the village of Radicofani. It is one of the most interesting examples of Romanesque-Gothic building in the Val d'Orcia and, unfortunately, has undergone major restoration work, especially in 1946, to repair the extensive damage caused by the Second World War.
The simple stone facade, set at the end of a flight of steps, has a 13th-century portal above which is a mullioned window.
On the left-hand side is the Church of Santa Maria Assunta, while on the right is the Corpus Christi Oratory. Opposite can be seen the Church of St. Agatha.
The jewel in the crown of the church are the numerous glazed terracotta masterpieces by Andrea Della Robbia, dated to the first half of the 1500s, such as La Crocifissione con Santa Maria Maddalena (The Crucifixion with St. Mary Magdalene), La Madonna col bambino in trono e i santi Michele e Caterina, La Madonna con Sant'Antonio Abbate e Giobbe (Our Lady and Child Enthroned and Saints Michael and Catherine, Our Lady with Saint Anthony Abbot and Job).
The interior, with a single nave and wooden truss roof, also contains a number of wooden statues in the style of Michelangelo and a polychrome wooden statue - Madonna and Child - attributed to Francesco di Valdambrino.
In the Maccione garden, next to the church, there is a statue depicting Ghino di Tacco, the gentleman bandit.
