Piazza della Rotonda Piazza della Rotonda The Piazza della Rotonda is a piazza (city square) in Rome, Italy, on the south side of which is located the Pantheon. The square gets its name from the Pantheon's informal title as the church of "Santa Maria Rotonda". Although the Pantheon has stood from antiquity, the area in front of it had over the centuries become choked with a maze of sheds and small shops that had grown up around its columns. These medieval accretions were cleared by order of Pope Eugenius IV (1431–39) and the piazza was laid out and paved. It took its name
Piazza Cordusio delle Poste (Palace of the Post Office), former Borsa di Milano" (former Milan Stock Exchange). Piazzale Cordusio hosts the Cordusio metro station and is the starting point of the elegant pedestrian Via Dante which leads to the imposing medieval Castello Sforzesco, or Milan Castle. Opposite to Via Dante, Cordusio borders onto Piazza Mercanti, former city centre in the Middle Ages, which leads directly to Piazza del Duomo, today's city centre. This palace is the main one in the square, and was built by architect Luca Beltrami from 1897 to 1901. It is the main headquarter of the mega-finance corporation Assicurazioni
