Ali Pasha Castle is named after Ali Pasha of Tepelenë who resided there until 1820. The current fortress was rebuilt in 1819 from its surface with 3 towers.
Built under Venetian dominion in the late 15th or early 16th century, it provided a stronghold for the Venetians on Corfu to exploit fishing, grazing, olives and timber in and around Butrint. The castle was the centrepiece of numerous conflicts with the burgeoning Ottoman Empire, and changed hands on several occasions. It was finally destroyed by a retreating French army in 1798 to prevent it falling into the hands of Ali Pasha.
The fortification attributed to Ali Pasha at Butrint lies some 2.4 kilometres due west at the mouth of the Vivari Channel. This in itself began life in the late 17th or early 18th century as a fortified estate centre belonging to a Corfiote family that farmed land on the plains south of the ancient city. Ali Pasha seized control of the structure around 1804 and carried out a series of defensive improvements including the installation of gun batteries. Given its small size it is unlikely that the fort functioned as anything more than a control over access from the sea to Butrint, and it can not be compared to Ali's more redoubtable fortresses in the region at Tepelena, Gjirokastra and Ioannina.References:
Derbent is the southernmost city in Russia, occupying the narrow gateway between the Caspian Sea and the Caucasus Mountains connecting the Eurasian steppes to the north and the Iranian Plateau to the south. Derbent claims to be the oldest city in Russia with historical documentation dating to the 8th century BCE. Due to its strategic location, over the course of history, the city changed ownership many times, particularly among the Persian, Arab, Mongol, Timurid, Shirvan and Iranian kingdoms.
Derbent has archaeological structures over 5,000 years old. As a result of this geographic peculiarity, the city developed between two walls, stretching from the mountains to the sea. These fortifications were continuously employed for a millennium and a half, longer than any other extant fortress in the world.
A traditionally and historically Iranian city, the first intensive settlement in the Derbent area dates from the 8th century BC. The site was intermittently controlled by the Persian monarchs, starting from the 6th century BC. Until the 4th century AD, it was part of Caucasian Albania which was a satrap of the Achaemenid Persian Empire. In the 5th century Derbent functioned as a border fortress and the seat of Sassanid Persians. Because of its strategic position on the northern branch of the Silk Route, the fortress was contested by the Khazars in the course of the Khazar-Arab Wars. In 654, Derbent was captured by the Arabs.
The Sassanid fortress does not exist any more, as the famous Derbent fortress as it stands today was built from the 12th century onward. Derbent became a strong military outpost and harbour of the Sassanid empire. During the 5th and 6th centuries, Derbent also became an important center for spreading the Christian faith in the Caucasus.
The site continued to be of great strategic importance until the 19th century. Today the fortifications consist of two parallel defence walls and Naryn-Kala Citadel. The walls are 3.6km long, stretching from the sea up to the mountains. They were built from stone and had 73 defence towers. 9 out of the 14 original gates remain.
In Naryn-Kala Citadel most of the old buildings, including a palace and a church, are now in ruins. It also holds baths and one of the oldest mosques in the former USSR.
In 2003, UNESCO included the old part of Derbent with traditional buildings in the World Heritage List.
