A rotating collection displayed over two floors recounts the evolution of the Eternal City from the Middle Ages to the early 20th century.

Paintings and drawings include portraits of Roman movers and shakers, and views of what the city looked like before 17th- and 19th-century building projects, such as the banchine flood walls along the Tiber, dramatically changed it.
Palazzo Braschi is a large, late Roccoco palace in Rome, Italy, designed by Cosimo Morelli. It is located between Piazza Navona, Campo de' Fiori (and Corso Vittorio Emanuele II), and the Piazza di Pasquino. It presently houses the civic museum of Rome (Museo di Roma). It was designed by Cosimo Morelli and built over a number of decades of the end of the 18th and beginning of the 19th century.

The main entrance is on Via San Pantaleo (between Piazza Navona and Corso Vittorio Emanuele). The oval hall at the main entrance overlooks via San Pantaleo, and leads to the monumental staircase with its eighteen red granite columns coming from the gallery built by emperor Caligula on the banks of the Tiber. Along the staircase there are ancient sculptures and fine stuccoes, inspired by Achilles’ myth. The architect Giuseppe Valadier probably contributed to its execution.
