Byllis was an ancient city located in the region of Illyria, today in Vlorë, 25 kilometers from the sea in Albania. Dating back to the 4th century BCE, it is one of the most important archeological sites in Albania.
The city, although a Greek speaking settlement was located on the territory of the Illyrian tribe of Bylliones. The later were first attested in the mid-4th century BC, in the description of the geographer Pseudo-Scylax, and also asking the oracle of Dodona to which god they should sacrifice in order to ensure the safety of their possessions. The archaeological attestation of the city is possible as far back as the second half of the 4th century BC and was later conquered by Pyrrhus. According to another view, Byllis was founded by king Pyrrhus of Epirus.
The walls of Byllis were 2,200m long, enclosing 30 hectares of a plain atop a hill 524m above sea level. There were 6 gates in the city walls. The road coming from Apollonia passed through two of them, crossing Byllis in the direction of the narrows of gorges of the Vjosa river on the way to Macedonia or those of Antigonia in the direction of Epirus. In 2011 during a road reconstruction near the archaeological park found in the site a statue of the Hellenistic era, which may depict an Illyrian soldier or a war deity, was discovered. However, there is little point in proposing an Illyrian label for city in which language, institutions, officials, onomastics, city-planning and fortifications were Greek.
Under the Roman Empire, Byllis became part of the province of Epirus Nova. Its name often occurs at the time of the civil wars. In the time of Pliny the Elder, it was a Roman colony, and was called Colonia Bullidensis. The walls of Byllis carry more than four inscriptions with details regarding their construction by the engineer Victorinus, as ordered by Emperor Justinian I (483-565).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.
