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:Considered to be one of the most imposing Roman ruins, Diocletian’s palace is certainly the main attraction of the city of Split. The ruins of palace, built between the late 3rd and the early 4th centuries A.D., can be found throughout the city. Today the remains of the palace are part of the historic core of Split, which in 1979 was listed by UNESCO as a World Heritage Site.
While it is referred to as a 'palace' because of its intended use as the retirement residence of Diocletian, the term can be misleading as the structure is massive and more resembles a large fortress: about half of it was for Diocletian's personal use, and the rest housed the military garrison.
Architecture
The palace has a form of an irregular rectangle with numerous towers on the western, northern, and eastern facades.
