Sarov (Russian: Саро́в) is a closed town in Nizhny Novgorod Oblast, Russia. Until 1995 it was known as Kremlyov (Кремлёв), while from 1946 to 1991 it was called Arzamas-16 (Арзама́с-16). The town is closed as 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, St. 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 Sarova Monastery next to the Sarovka 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, the monks faced Bolshevik repressions, and many were executed. 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. The town, initially called Arzamas-75, later renamed Arzamas-16, was removed from all unclassified maps. In 1954, Arzamas-16 was granted town status.
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. A small airport on the facility 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.
In 1993, the town became a sister city to Los Alamos, New Mexico, the home of the U.S. nuclear weapons design laboratory (Los Alamos National Laboratory, or LANL). Scientists from LANL and VNIIEF have cooperated on various arms control and nuclear safeguards programs, under which the Los Alamos scientists learned, to their amusement, that their Russian colleagues paid homage to their American rivals by irreverently calling their own laboratory "Los Arzamas."
Boris Yeltsin changed the town's name back to Sarov at the request of the residents in August 1995.
Today the Russian federal nuclear center is responsible for important decisions concerning the development, production, storage, and utilization of nuclear weapons; the recycling of radioactive and other materials; and research in fundamental and applied physics.
Administrative and municipal status 
Within the framework of administrative divisions, it is incorporated as the town of oblast significance of Sarov—an administrative unit with the status equal to that of the districts. As a municipal division, the town of oblast significance of Sarov is incorporated as Sarov Urban Okrug.
