The Mount Ursino Castle was destroyed by a fire around 900 and rebuilt on the hill. It is mentioned in 1004 in a document and defined fortified village. After the construction of a first tower on top of the hill, the fortress was enlarged repeatedly until reaching its present form around the 15th century, embracing even the baby village in the Piana, current historical center, while it was gradually abandoned that in hill. Supporters of this structure medieval military were mainly the Del Carretto family, the feudal lords of Noli. The castle was able to control both the sea and the coast that the old Roman road passing in the hill in the locality of Voze, and used until the 18th century.
The castle is formed on the top by a cylindrical tower, surrounded by massive walls and from the accommodation for the troop. From this main core descended two walled perimeters, largely still preserved today, which embraced the whole hill and subsequently also the village downstream. Circular towers susseguivano it at regular intervals along the sloping walls on the sides of the Monte Ursino. The access doors were defended by a singular system still today partly preserved that was constituted by an external tower to walls and connected thereto via a walkway in masonry. This allowed to defend the access doors from the outside by hitting enemies from behind. The castle and the walls of the village are among the examples of medieval fortification best preserved in the Ligurian Ponente.
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.
