The Palazzo Poli is a palace in Rome, Italy, that was altered in the 18th century to form the backdrop to the Trevi Fountain.

The Conti family was responsible for many more extensions, including purchasing and incorporating of many adjacent buildings which formed the Piazza di Trevi.

As a setting for the fountain, Vanvitelli gave the building a new monumental façade that contains the giant order of Corinthian pilasters linking the two main storeys of the palace.

Maria Cristina Misiti, director of the National Institute of Graphics, had the idea to turn the building into a museum to help visitors learn more about the history of Rome and its inhabitants.
