The Pyramid of Cestius is an ancient pyramid in Rome. Due to its incorporation into the city's fortifications, it is today one of the best-preserved ancient buildings in Rome.
The pyramid was built about 18–12 BC as a tomb for Gaius Cestius, a magistrate and member of one of the four great religious corporations in Rome, the Septemviri Epulonum. The sharply pointed shape of the pyramid is strongly reminiscent of the pyramids of Nubia, in particular of the kingdom of Meroë, which had been attacked by Rome in 23 BC. The similarity suggests that Cestius had possibly served in that campaign and perhaps intended the pyramid to serve as a commemoration.
The pyramid is of brick-faced concrete covered with slabs of white marble standing on a travertine foundation. The pyramid measures 29.6 m square at the base and stands 37m high.
In the interior is the burial chamber, a simple barrel-vaulted rectangular cavity. When opened in 1660, the chamber was found to be decorated with frescoes, which were recorded by Pietro Santi Bartoli. Only scant traces of these frescoes survive, and no trace of any other contents. The tomb had been sealed when it was built, with no exterior entrance, but had been plundered at some time thereafter, probably during antiquity. Until the end of restoration works in 2015, it was not possible for visitors to access the interior, except by special permission typically only granted to scholars. Since the beginning of May 2015, the pyramid is open to the public every second and fourth Saturday each month. Visitors must arrange their visit in advance.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.
