Built on the promontory of the Arbostora, the origins of the ancient Morcote castle are unknown. It was probably built originally in the 12th century. Today, only the central part and the ruins remain, but what we do know is that it was a glorious military and civil feat of engineering.
From 1400 onwards, the fortress underwent many changes. The turning point came on February 18 1517, when the castle was donated by the confederate states to Francesco Paleari di Morcote, known as Fratino, with the proviso to demolish the military construction. And so the fort became an actual mine between the 16th and 19th century, as the municipality and noble families pilfered its materials to build the bell tower and expand the Church of Saint Maria del Sasso. The ancient fortress featured two underground tunnels for the fortress’ defenders to communicate with allies outside, beyond the boundary walls: the first connected the fortress with the village tower, the second came out near Figino. The fortress, built using massive stones, boasted two main parts: the central one was the ‘castle’, i.e. where the noble occupants resided; the two wings, with a tower at the sides, was the fortress proper. The walls of the whole area were extremely wide, had battlements built in the Ghibellini style with dovetail joints, defensive towers and extended east and west to reach the shore of the lake enclosing the village.
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.
