The Baroque church of Santa Rosalia in Palestrina, designed by Contini, is englobed in the architectonic structure of the Palazzo Colonna Barberini.
It was built and opened as a place of worship in 1660 and was dedicated to Santa Rosalia by Maffeo Barberini, after the town of Palestrina was miraculously saved from the plague between 1656 e il 1657.
Inside, the church is decorated with marble and stucco. The sepulchral monuments positioned on the side walls are by Caminetti and by two nephews of Pope Urban VIII, Taddeo Barberini and Cardinal Antonio Barberini. Over the central altar, there is a canvas, attributed to a F. Reali, which portrays Santa Rosalia in the act of protecting the city of Palermo from the plague.
The church once housed the famous Piety of Palestrina, attributed to Michelangelo, which is now exhibited in the Gallery of the Academy in Florence.
