Take a trip into the historical memory of Valtellina. You will find fortifications on rocky outcrops, such as the medieval Castel Masegra in Sondrio or, not far away, Castello Paribelli in Albosaggia.  While the ruins of Castel De Piro al Grumello in Montagna in Valtellina overlook the terraced vineyards that produce the red wine of the same name, Valtellina Superiore DOCG, the “De li Beli Miri” Tower dominates Valtellina from the Teglio hill. In central Piazza Cavour in Bormio, you will come across the medieval Torre delle Ore and, nearby, the Castello De Simoni, today the town hall, while in Valchiavenna, between Gordona and Samolaco, there is Segname Tower, still intact. From Valdidentro to Teglio, from Valmalenco to Chiuro, through to Mello: many places stand as testimony to the past, including the towns of Chiavenna and Tirano, with the remains of the walls that Ludovico il Moro had built. Finally, do the rounds of the defence works from World War One, like Forte Venini di Oga in Valdisotto or Forte Montecchio Nord and the Fuentes fort in Colico, or the San Fedele lead mine tunnel in Verceia.
