The 16th-century collegiate church is the main artistic site to see in Radicondoli, Inside, there are paintings by some of the most important members of the Sienese school, including Alessandro Casolani and Pietro di Domenico. The former is responsible for the Nativity and Death of the Virgin, while the latter painted the altarpiece with the Assumption of the Virgin and the Nativity. Domenico’s paintings were made in the late 1400s and stands out for the clear distinction between the upper part (Assumption) and the lower section (Nativity) atop the same background.
In addition to these paintings, other things worth seeing are the Madonna and Child by Niccolò di Ser Sozzo and the Romanesque Parish Church of S. Simone, with its single nave and interesting apse which serves as the cemetery’s mortuary chapel. Radicondoli’s artistic heritage also includes the Church of Santa Caterina d’Alessandria. The high altar conserves a canvas painting (1607) by Sebastiano Folli, a masterwork that exudes a strong sense of theatricality, with its colours and figures skillfully blended in the typical late-Roman Baroque style.
