Closed city in the context of "Dikson (urban-type settlement)"

Sevastopol (/ˌsɛvəˈstoʊpəl, sɪˈvæstəpoʊl/ SEV-ə-STOH-pəl, siv-AST-ə-pohl), sometimes written Sebastopol, is the largest city in Crimea and a major port on the Black Sea. Due to its strategic location and the navigability of the city's harbours, Sevastopol has been an important port and naval base throughout its history. Since the city's founding in 1783, it has been a major base for Russia's Black Sea Fleet. During the Cold War of the 20th century, it was a closed city. The total administrative area is 864 square kilometres (334 sq mi) and includes a significant amount of rural land. The urban population, largely concentrated around Sevastopol Bay, is 479,394, and the total population is 547,820.

Sevastopol, along with the rest of Crimea, is internationally recognised as part of Ukraine, and under the Ukrainian legal framework, it is administratively one of two cities with special status (the other being Kyiv). However, it has been occupied by Russia since 27 February 2014, before Russia annexed Crimea on 18 March 2014 and gave it the status of a federal city of Russia. Both Ukraine and Russia consider the city administratively separate from the Autonomous Republic of Crimea and the Republic of Crimea, respectively. The city's population has an ethnic Russian majority and a substantial minority of Ukrainians and Crimean Tatars.

Samara, formerly known as Kuybyshev (1935–1991), is the largest city and administrative centre of Samara Oblast in Russia. The city is located at the confluence of the Volga and the Samara rivers, with a population of over 1.14 million residents, up to 1.22 million residents in the urban agglomeration, not including Novokuybyshevsk, which is not conurbated. The city covers an area of 541.4 square kilometers (209.0 sq mi), and is the eighth-largest city in Russia and tenth agglomeration, the third-most populous city on the Volga, as well as the Volga Federal District.

Formerly a closed city, Samara is now a large and important social, political, economic, industrial, and cultural centre in Russia and hosted the European Union—Russia Summit in May 2007. It has a continental climate characterised by hot summers and cold winters. The life of Samara's citizens has always been intrinsically linked to the Volga River, which has not only served as the main commercial thoroughfare of Russia throughout several centuries, but also has a great visual appeal. Samara's riverfront is one of the main recreation sites for both local citizens and tourists.

Pripyat, also known as Prypiat, is an abandoned industrial city in Kyiv Oblast, Ukraine, located near the border with Belarus. Named after the nearby river, Pripyat, it was founded on 4 February 1970 as the ninth atomgrad ('atom city', a type of closed city in the Soviet Union that served the purpose of housing nuclear workers near a plant), catering the nearby Chernobyl Nuclear Power Plant. The plant is located north of the abandoned city of Chernobyl, after which it is named. Pripyat was officially proclaimed a city in 1979 and had ballooned to a population of 49,360 by the time it was evacuated on the afternoon of 27 April 1986, one day after the Chernobyl disaster.

Although it is located in Vyshhorod Raion, the abandoned municipality is administered directly from the capital of Kyiv. Pripyat is supervised by the State Emergency Service of Ukraine which manages activities for the entire Chernobyl exclusion zone. Following the 1986 Chernobyl nuclear disaster, the entire population of Pripyat was moved to the purpose-built city of Slavutych.
