The Roman Forum was once Ancient Rome’s district of basilicas, public spaces, and temples, that made up the Roman Empire’s political, commercial, and social center. It is located in a valley between Capitoline and Palatine Hills. When the Roman Empire fell, the Forum did as well. Much of its stone and marble was removed and reused elsewhere. It was used as pastureland in the Middle Ages, and in the 1800s excavations began, which continue even today. The Roman Forum is world-famous and a popular tourist destination because it was the forum in Ancient Rome that held the Senate House, making it the most important. The Roman Forum’s size was 170-meters by 250-meters. Some of the most famous ruins in the Roman Forum include the Temple of Vesta, the Temple of Saturn, the Arch of Titus, the Rostra, the Temple of Castor and Pollux, and the Curia, the Senate House.
