Rome
Piazza Navona in Rome.
"Defined as a public space in the last years of the 15th century, when the city market was transferred to it from the Campidoglio, the Piazza Navona is now the pride of Baroque Roman art history. It features sculptural and architectural creations by Gian Lorenzo Bernini, whose famous Fontana dei Quattro Fiumi (Fountain of the Four Rivers, 1651) stands in the center; by Francesco Borromini and Girolamo Rainaldi, who designed the church of Sant'Agnese in Agone; and by Pietro da Cortona, who painted the galleria in the Pamphilj palace." – Wikipedia
