Castelli are traditional Italian castles, often found in picturesque landscapes. They were built during the Middle Ages for defense and as residences for nobility. Many castelli feature impressive architecture, including towers, thick walls, and moats, reflecting the styles of their time. Today, many castelli serve as historical sites, attracting tourists interested in history, architecture, and Italian culture. Some have been restored and converted into hotels or museums, allowing visitors to experience the grandeur of the past while enjoying the scenic surroundings.
