Palazzo della Cancelleria

The Palazzo della Cancelleria is a Renaissance palace in Rome, Italy, situated between the present Corso Vittorio Emanuele II and the Campo de' Fiori, in the rione of Parione. It was built 1489–1513 by Baccio Pontelli and Antonio da Sangallo the Elder as a palace for Raffaele Cardinal Riario, Camerlengo of the Holy Roman Church, and is regarded as the earliest Renaissance palace in Rome.

The Palazzo houses the Papal Chancellery, is an extraterritorial property of the Holy See, and is designated as a World Heritage Site.
