The Fortino di Mazzallakkar is a ruined Arab fort in Sambuca di Sicilia. It is located near Lago Arancio, and is partially submerged by its waters for six months of every year.
The Fortino di Mazzallakkar was built by the Arabs in around 830 AD, possibly to defend the territory around Sambuca di Sicilia, which was then known as Zabut.
The fort was still in good condition until the mid-20th century, and it was used as a shelter for sheep and cattle. In the 1950s, the Carboj dam was built, causing the flooding of Lago Arancio. The fort is located at the edge of the lake, and is partially submerged around 6 months of the year. This has caused a lot of damage to the fort.
The fort is privately owned, and can be visited on request.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
