The Castello di Frascarolo (Frascarolo castle) or of Medici of Marignano is on the hill on a dominating position between Ganna and Ceresio valleys.
It is believed the castle is from the early Middle Ages, perhaps the work of the Longobards, but it’s only documented in 1160 when Archbishop of Milan Oberto da Pirovano upheld a valid resistance to the advancing inhabitants of Como looking to conquer the Varese area. However, it’s possible that the castle was only a rural fort back then.
Starting in the 12th century, it was the property of the Abbey of Ganna (or Abbey of San Gemolo in Ganna Valley), and followed destiny and plunders including the one by the Swiss Unterwalden from Mendrisio in 1511; it was purchased by Marquis of Marignano Gian Battista Medici in 1543. It was precisely with the advent of the noble Medici family that the castle was renovated and embellished. Over the centuries, it lost its defensive physiognomy to become a typical 16th-century residence.
The castle and its massive walls flaunt a mighty 15th-century tower with a rusticated portal, courtyard with a loggia, and an adjacent section built in the 16th century when it became an exclusive dwelling. The entrance hall preceded by a boulevard and large stretches of meadow inside certainly belong to another period.
The castle is still private property and cannot be toured without specific permission.
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.
