Tower introduction: The black and white towers (Torre Nera & Torre Bianca) in the Grande Castle are like two castle guardians, guarding the castle. The twin towers were used as bow and arrow launching towers for guards in the past. People at the time believed that, Such a strong city defense is enough to resist the invading "Northern Enemies". Today's twin towers have become an excellent place for overlooking. When the weather is clear, you can enjoy the panoramic view of Bellinzona surrounded by white clouds and green mountains.
