The Roman city of Cemenelum was founded in the 1st century AD as a staging post for Roman troops in the Alpes Maritime region and it later became the regional capital. Favorably located, Cemenelum was chosen as the principal seat of the province of Alpes Maritimae by Augustus in 14 BC. Later, the Romans settled further inland, on the opposite side of the river Paillon. Remains of the town on the Hill of Cimiez date to the 3rd century AD.
The Amphitheater at the northern end of the site was originally built of wood and seated only 500-600. It was later rebuilt in stone during the Severan dynasty (AD 193-217) with its capacity expanded to 5000 persons. The vaulted remains at Nice may be compared to other small amphitheaters in garrison towns in the Roman Empire. Seating in the amphitheater reflected class distinctions between officers and enlisted men, with the structure at Nice-Cimiez divided into two sections reached by separate entrances.
The amphitheatre is not as big or as well-preserved as those found in Arles or Nimes, but along with the Roman baths and arena, visitors can gain a sense of wonder into Roman life by paying a visit to the archaeological museum (Musée Archéologique de Nice-Cimiez) on Avenue des Arènes.
The Roman baths complex is the largest known in Gaul.
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.
