Closed city

 

Closed cities are sometimes represented only on classified maps that are not available to the general public.^[1] In some cases, there may be no road signs or directions to closed cities, and they are usually omitted from railroad timetables and bus routes.

Sometimes, closed cities are indicated obliquely as a nearby insignificant village, with the name of the stop serving the closed city made equivocal or misleading. For mail delivery, a closed city is usually named as the nearest large city and a special postcode, for example, Arzamas‑16, Chelyabinsk‑65. The actual settlement can be rather distant from its namesakes; for instance, Sarov, designated Arzamas-16, is in the federal republic of Mordovia, whereas Arzamas is in Nizhny Novgorod Oblast (roughly 75 kilometres (47 mi) away). People not living in a closed city were subject to document checks and security checkpoints, and explicit permission was required for them to visit.^[3] To relocate to a closed city, one would need security clearance by the organization running it, such as the KGB in Soviet closed cities.

Closed cities were sometimes guarded by a security perimeter with barbed wire and towers. The very fact of such a city's existence was often classified, and residents were expected not to divulge their place of residence to outsiders. This lack of freedom was often compensated by better housing conditions and a better choice of goods in retail trade than elsewhere in the country.^[1] Also, in the Soviet Union, people working with classified information received a salary bonus.^{[citation needed]}

 

Closed cities were established in the Soviet Union from the late 1940s onwards under the euphemistic name of "post boxes", referring to the practice of addressing post to them via mailboxes in other cities. They fell into two distinct categories.

1. The first category comprised relatively small communities with sensitive military, industrial, or scientific facilities, such as arms plants or nuclear research sites.^[4] Examples are the modern towns of Ozyorsk (Chelyabinsk-65) with a plutonium production plant, and Sillamäe, the site of a uranium enrichment facility. Even Soviet citizens were not allowed access to these places without proper authorization. In addition to this, some bigger cities were closed for unauthorized access to foreigners, while they were freely accessible to Soviet citizens. These included cities like Perm, a center for Soviet artillery, munitions, and also aircraft engines production, and Vladivostok, the headquarters and primary base of the Soviet Pacific Fleet.
2. The second category consisted of border cities (and some whole border areas, such as the Kaliningrad Oblast,^{[citation needed]} Saaremaa, and Hiiumaa), which were closed for security purposes. Comparable closed areas existed elsewhere in the Eastern bloc; a substantial area along the inner German border and the border between West Germany and Czechoslovakia was placed under similar restrictions (although by the 1970s foreigners could cross the latter by train). Citizens were required to have special permits to enter such areas.

The locations of the first category of closed cities were chosen for their geographical characteristics. They were often established in remote places deep in the Urals and Siberia, out of reach of enemy bombers. They were built close to rivers and lakes that were used to provide the large amounts of water needed for heavy industry and nuclear technology. Existing civilian settlements in the vicinity were often used as sources of construction labour. Although the closure of cities originated as a strictly temporary measure that was to be normalized under more favorable conditions, in practice the closed cities took on a life of their own and became a notable institutional feature of the Soviet system.^[5]

Any movement to and from closed areas was tightly controlled. Foreigners were prohibited from entering them and local citizens were under stringent restrictions. They had to have special permission to travel there or leave, and anyone seeking residency was required to undergo vetting by the NKVD and its successor agencies. Access to some closed cities was physically enforced by surrounding them with barbed wire fences monitored by armed guards.

"Mailbox" (Russian: Почтовый ящик, romanized: Pochtovyy yashchik) was the unofficial name of a secret Soviet facility much like the closed city, but smaller, usually the size of a factory. The name of such a facility was usually secret, as were the activities there. Incoming mail was addressed to "Mailbox #XXXX", thus the name of "mailbox". Most Soviet design bureaus (OKB) for weapons, aircraft, space technology, military electronics, etc., were "mailboxes".^{[citation needed]}

 

Russia has the largest number of closed cities globally. The policy governing these cities underwent significant changes in the late 1980s and early 1990s. The adoption of a new constitution for the Russian Federation in 1993 prompted substantial reforms to the status of closed cities, which were subsequently renamed "closed administrative-territorial formations" (or ZATO, from the Russian acronym). Municipally, all such entities have the status of urban okrugs, as mandated by federal law.

There are 44 publicly acknowledged closed cities in Russia with a total population of approximately 1.5 million people. Seventy-five percent are administered by the Russian Ministry of Defense, with the remainder under the administration of Rosatom.^[6] It is believed that about 15 additional closed cities exist, but their names and locations have not been publicly disclosed by the Russian government.^[7]

Some Russian closed cities are open to foreign investment, but entry for foreigners requires a permit. An example of international cooperation in these cities is the Nuclear Cities Initiative (NCI), a joint effort of the United States National Nuclear Security Administration and Minatom, which involves, in part, the cities of Sarov, Snezhinsk, and Zheleznogorsk.

The number of closed cities has been significantly reduced since the mid-1990s. However, on 30 October 2001, foreign travel was restricted without exception in the northern cities of Norilsk, Talnakh, Kayerkan, Dudinka, and Igarka. Russian and Belarusian citizens visiting these cities are not required to have permits; however, local courts have been known to deport Belarusian citizens.^[8]

There were two closed cities in Estonia: Sillamäe and Paldiski. As with all the other industrial cities, their population was mainly Russian-speaking. Sillamäe was the site for a chemical factory that produced fuel rods and nuclear materials for the Soviet nuclear power plants and nuclear weapon facilities, while Paldiski was home to a Soviet Navy nuclear submarine training centre. Sillamäe was closed until Estonia regained its independence in 1991; Paldiski remained closed until 1994, when the last Russian warship left.^[20]

Tartu, home to Raadi Airfield, was partially closed. Foreign academics could visit the University of Tartu, but had to sleep elsewhere.

 

• Baikonur, a town close to the Baikonur Cosmodrome in Kazakhstan, which is rented and administered by Russia. Non-resident visitors will need pre-approval from the Russian authorities to visit both the town of Baikonur itself and the Cosmodrome. Note that said approval is completely separate from just having a Russian visa. Some tourism organisations in Kazakhstan provide services in organising trips to visit Baikonur and the museums contained there.
• Priozersk, Kazakhstan^[21]
• Kurchatov, Kazakhstan^[22] – a former closed city that known by its postal code, Semipalatinsk-21.^[23]

• Mailuu-Suu, Jalal-Abad Region, a formerly closed uranium mining town, once known as "Mailbox 200".^[24]

• Karosta, a former Russian and Soviet naval base.
• Skrunda-1, a former Soviet communications base. Currently used by the Latvian Armed Forces as of 2022.

Moldova has one partially closed city: the village of Cobasna (Rîbnița District), which is under the control of the unrecognized state of Transnistria internationally recognized as part of Moldova. The village, on the left bank of the Dniester river, contains a large Soviet-era ammunition depot guarded by Russian troops.^[25][26] Only the Transnistrian and Russian authorities have detailed information about this depot.^[27]

Ukraine had eighteen closed cities, including:

• Dnipro – former closed city, a major center of Soviet aerospace industry.
• Simferopol-28, Crimea – former closed town, a Soviet military space mission control center.
• Kamianske – former closed city, largest Uranium processing factory in former Soviet Union.^[28]

During the period of communist rule in Albania, the towns of Çorovodë and Qyteti Stalin (now Kuçovë) were closed cities with a military airport, military industry and other critical war infrastructure.

• Arnhem Land is a historical region of the Northern Territory which requires permits for access to non-Aboriginal individuals beyond public roads.^[29]
• Puckapunyal is a restricted-access town in a military area in Victoria, home to some 250 families.

• No. 404 Factory of China National Nuclear Corporation (中国核工业总公司第四零四厂), then the Ministry of Nuclear Industry, in the Gobi desert in the western part of Gansu, is a closed town often called the nuclear town (核城). Built in 1958, it is China's biggest nuclear industry base. China built its first military nuclear reactor^[30][31] there and 80% of the core parts for China's nuclear bombs were produced there. Until the 1980s, the whole town was closed to outsiders.^[32] A nuclear accident happened in 1969, involving a leak.^[33] The name "mine area of Gansu" (甘肃矿区) was used for secrecy. In 2007, most residents were moved to nearby Jiayuguan City.
• Some remote areas in China, such as Datong Hui and Tu Autonomous County (except Laoye Mountain), Huangzhong County (except Kumbum Monastery), and Huangyuan County around Xining, the capital of Qinghai, maintain travel restrictions for foreigners. A foreigner must apply for an alien travel document (外国人旅行证) in advance, and report their accommodation to local police within 24 hours after entering the area.^[34]

• Riems, Germany, an island in the Bay of Greifswald, is home to the oldest virological research institution in the world and is closed to the public. Quarantine stables and laboratories have a high level of security. This means employees and visitors to the complex must change their clothes and shower when entering and exiting.

 

The Frontier Closed Area (FCA) is a restricted zone along the northern border of Hong Kong, serving as a buffer between the closed border and the rest of the territory. Access to this area requires a Closed Area Permit. From 1951 to 2012, the FCA encompassed an area of 28 square kilometres, containing numerous villages. Following several stages of reduction, by 2016, the border town of Sha Tau Kok remained as the sole settlement within the FCA.

Within the Korean Demilitarized Zone between North Korea and South Korea are two "peace villages" (one maintained by each nation): Daeseong-dong (South) and (possibly) Kijŏng-dong (North). Access by non-residents to Daeseong-dong requires a military escort, while Kijŏng-dong is not accessible to visitors.

The Yongbyon Nuclear Scientific Research Center sits within a closed city that occupies 24.8 square kilometers (9.6 sq mi).^[35] The classification of a city being closed or not closed is dubious in a North Korean context, as North Korean citizens generally need a permit if they wish to travel outside of their county,^{[citation needed]} and further permits required for entry to Pyongyang,^{[citation needed]} thus the whole nation could be considered closed.

• In Baja California, the communities on Guadalupe Island (such as Campo Oeste) can be considered closed towns; because Guadalupe Island is within a Biosphere Reserve, the Mexican government requires special permits in order to visit the island.^[36][37][38]

• Mecca is strictly closed to non-Muslims. Similar restrictions are in place for the city center of Medina.^[39][40]

• Alexander Bay, Northern Cape. After diamonds were discovered along this coast in 1925 by Hans Merensky, Alexander Bay became known for its mining activities. The town was a high-security area and permits were needed when entered. Today, it is no longer a high-security area and no permits are needed.

• Fårö and the northernmost parts of Gotland were closed to foreign citizens until 1998.^[41]

• Imber, England, has been closed since 1943 when its residents were evicted by the British Army, who continue to use the village as a training ground for urban warfare. While most of the village's buildings have been demolished and replaced for training purposes, the village church (St Giles') was kept intact and the village is occasionally opened to the public during holidays.
• Foulness Island contains two villages with permanent residences, but public right of way is limited to certain paths and access controlled by the Ministry of Defence.
