Piazza di Sant'Ignazio

Between the Pantheon and Via del Corso. A stunning example of Baroque art. The ceiling frescoes are especially fine, including a trompe l'oeil dome by the master Andrea Pozzo.

The temple of the Emperor Hadrian was consecrated in 145 AD by Emperor Antoninus Pius. The remains of the antique temple were incorporated into a new building that served as the Papal Customs House. It was finished around 1690 and today accommodates the Stock Exchange (Borsa).

The Collegio Romano was a college of the Jesuit order. Many popes, cardinals and bishops were educated here. Since 1870 it has been a secular (non-monastic) school. The coat of arms on the doorway is that of Pope Gregory XIII (1572–1585). The tower was erected in 1787 and served as an observatory. Until 1925 all clocks in Rome were set after that of the Collegio Romano.

An ancient Egyptian obelisk brought to Rome in 10 BC.

This church is literally right next to the Pantheon. It is one of Rome's only Gothic churches, and well worth looking inside, although its plain square façade makes it look inconspicuous from outside. Excellent stained glass windows.
