Abstract/Hauptbeschreibung (Englisch)

In the 18th century the Church of the Assunta in Rocca di Papa was built and decorated, starting from a building that had just begun in the previous century. The article reconstructs these events based on many new documentary sources and a accurate analysis of the still existing works. Although the church was in a peripheral position, the powerful Cardinal Pietro Ottoboni, bishop of the diocese of Frascati, granted his protection; so the church was designed by his architects Pietro Passalacqua and Domenico Gregorini, and was partly built by two important Roman master builders. A plan relating to the nineteenth-century reconstruction, allows us to better understand the structure in the eighteenth century. The building was decorated with paintings in part from the destroyed church of S. Maria degli Angeli and in part with paintings specially executed, among which the famous Assumption of Corrado Giaquinto.
