Sarov

Sarov (Russian: Саро́в) is a closed town in Nizhny Novgorod Oblast, Russia. It was known as Gorkiy-130 (Горький-130) and Arzamas-16 (Арзама́с-16), after a (somewhat) nearby town of Arzamas, from 1946 to 1991. Until 1995, it was known as Kremlyov/Kremlev/Kremljov (Кремлёв). The town is closed because it is the Russian center for nuclear research. Population: 92,047 (2010 Census); 87,652 (2002 Census)

The history of the town can be divided into two different periods. In the earlier history of Russia it was known as one of the holy places of the Russian Orthodox Church, because of its monastery, that gave Russia one of its greatest saints, Saint Seraphim. Since the 1940s, it has gradually become the center for research and production of Soviet and later Russian nuclear weapons.

The history of human settlement in the area around Sarov goes back at least to the 12th–13th centuries, when a large Mordvin settlement was founded on its spot. In 1298, the town was taken over by Tatars.

The modern town took its name from being the site of the Sarov Monastery next to the Sarov River. In 1664, an Orthodox monk Theodosius first settled on the Sarov hill. The first Church of Sarov tenement was founded in 1706. Saint Seraphim was living in Sarov from 1778 to 1833. In 1903, the monastery was visited by Tsar Nicholas II and other members of the royal family. At that time the monastery had nine churches, including one underground. Around 320 monks lived in the monastery.

In 1923, the monastery was closed, and the monks were executed by the Bolsheviks. During World War II, the monastery buildings were used as factories for producing rockets for BM-13 "Katyusha" rocket launchers.

In 1946, the All-Union Scientific Research Institute of Experimental Physics—a nuclear weapons design facility that would become known in the West under the acronym VNIIEF—was built. Sarov became a closed city. It was removed from all unclassified maps. Initial provisional names included Base 112, Site 550, Yasnogorsk, Kremlyev and Arzamas-75. Sarov was known as Arzamas-16 until 1995. In 1954, Arzamas-16 was granted town status.^{[citation needed]}

The town is home to the Russian Federation Nuclear Center and "Atomic Bomb" museum which has a number of casings of Soviet-era nuclear weapons and photographs of those involved in their production. The main access is by train, which, after a security stop and inspection, is allowed into the town to disembark passengers. The small Sarov Airport is generally for government aircraft only, and visitors usually fly to Nizhny Novgorod airport and then drive.

The town is surrounded by fences patrolled by the military. Foreigners, and even Russians who do not live in Sarov, are not allowed to enter the town without permission. Foreigners who visit on business must surrender their passports, phones, and cameras to security while they are in the facility, though some documentary filmmakers have shot footage inside the town walls.
