The Venetian Fortifications are a series of defensive structures built by the Republic of Venice from the 15th to the 17th centuries. These fortifications were designed to protect the city of Venice and its territories from invasions and naval attacks. They include walls, bastions, and towers, showcasing advanced military architecture of the time. Many of these fortifications are located on various islands and coastal areas, including Verona and Corfu. The Venetian Fortifications are recognized for their strategic design and historical significance, and several sites are now designated as UNESCO World Heritage Sites, reflecting their importance in European military history.
