The origins of this palace is connected to the Tignosi family. The architectural characteristics of the main entrance and courtyard indicate that the foundation was created during the second half of the 13th century.
The Palazzo Papale (Papal Palace) was built on commission by Raniero Gatti in the year 1266. The purpose was to provide the pontiffs of town guests a secure dwelling. This decision coincided with the initiative undertaken in 1257 by Alexander IV, who was concerned about the present political instability in Rome. He saw it best to transfer the base of the Pope in the city, where it would be easier to rearrange the Guelph resistance.
