The elegant Piazza del Popolo in Rome started as a trapezoidal piazza in 1538 and contains a 3,200 year old obelisk from Heliopolis. Renaissance and Baroque art, architecture and sculpture can be found in the spectacular Santa Maria del Popolo church. Masters from the Early Renaissance (Pinturicchio, Bramante), High Renaissance (Raphael) and Baroque (Caravaggio, Bernini) exercised their genius in all disciplines here. Beyond the city walls is Rome‘s second largest church, the San Paolo fuori le Mura, over the spot where St. Paul was buried. For about 400 years, it was the largest church in Europe.
