Inspired by the splendour of the 16th century palaces, Palazzo Massimo is not only an architectural feat but an artistic one. Stop by to spot some of the most well-preserved Roman frescoes in the world. 

A beautiful small church designed by Baroque architect Francesco Borromini. While the whole building fits exactly into one of the dome piers of Saint Peter's, it is totally worth a visit. From the crossing outside (watch out for the traffic!) you can see an obelisk at the end of each of the four roads. 

This beautiful hidden spot specialises in the original Rosetta: the eggplant and basil parmigiana sandwiched in crispy light roman bread and a Peroni on the side, is our go-to order.
