The Piazza del Foro is one of the oldest squares in Brescia, born on the hole in the Roman city of the 1st century BC. It is part of the Brescia Antica district, in the heart of the historic center, crossed north by via dei Musei. It is rectangular and contains most of the Roman remains of the city, divided between the Capitolium, the civilian basilica and the archaeological excavations of Palazzo Martinengo Cesaresco Novarino. As evidenced by some archaeological studies of the remains of the Martinengo palace, the square had its greatest splendor in Roman times. The ancient Roman forum has been attributed many to the center of the civil and religious life of the Roman Brixia, as evidenced by the presence of the Capitoline Temple, located in the northern part of the square, which included two rows of lateral arcades of which there were some A sign in the central part of the square, and the Basilica (or court), of which some remains are found in the surrounding buildings. A further demonstration of the centrality that this square occupies in the life of ancient Brixia Romana is the presence of the ancient Decumano Massimo, an ancient town road that allowed connections with the other inhabited areas of the area on the Bergamo-Verona axis, the one that Currently it is Via Musei, which divided the square from another Roman building, though from the time of the next, the theater. Located on the slopes of the Cidneo hill, the square, which has a sloping southward slope, is an example of the unity of various architectures that Brescia has experienced over the years. Along with the buildings of Roman times, there are post-Renaissance buildings and subsequent periods, while there are few testimonies of the medieval period, perhaps due to the gradual abandonment of these places by the citizens of the time to prefer the "new" areas of the current square Paul VI and Victory Square. In fact, in the northern part, at the opposite corners formed by the intersection with Via Musei, there are two examples of post-seventeenth century architecture such as the church of San Zeno al Foro, built in 1745, and the noble Martinengo palace, built by Cesare IV Martinengo Cesaresco Towards the middle of the seventeenth century on the basis of a previous building, where an archaeological trail can be visited, which holds testimonies from the Iron Age to the Low Middle Ages, obviously passing through the Roman age. Along the Decumano, and in the neighboring areas of the square, there are many Renaissance palaces, such as Maggi di Gradella palace, Lana palace, Uggeri palace and Maggi Gambara palace, made by Brescia's architect Lodovico Beretta.
