VIA FEDERICO PATETTA 49
At your left, there's the church of Santa Maria del Popolo, restored in 1660 by Bernini, that hosts two masterpieces of Caravaggio.
At the other side, there are the twin churches of Santa Maria in Montesanto (1675) and Santa Maria dei Miracoli (1678).
At the center of the square, the obelisk, dated 1200 BC, was brought in Rome by Augustus and set in that place by Sixtus V in 1589.
The present design of the square is a work of the architect Valadier.
