Montalto Dora Castle was built in the first half of the 12th century on top of Monte Crovero reflecting in the waters of Lake Pistono, being first mentioned under the name of castrum monsalti in a document dating from 1140.
During the 14th and 15th century, the castle was modified and enlarged to better serve from a defensive viewpoint.
In the 19th century, the castle was renovated under the direction of architects Carlo Nigra and Alfredo d'Andrade, who also used it as a model and source of inspiration when designing the Borgo Medioevale in Turin.
In 1963 the Castle became property of the Allioni of Brondello family. From 1965 to 1985 they proceeded to restore the buildings inside the walls, and to enhance the park.In the last years, the current owners have gone on completing a functional restoration of internal and external spaces, along with several enhancing works for the whole park and its vegetation.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
