Sevastopol or traditionally Sebastopol (/sɛvəˈstoʊpəl, -ˈstɒpəl/ or /sɛˈvæstəpəl, -pɒl/Russian: Севасто́поль, Ukrainian: Севасто́поль ; Crimean Tatar: Акъяр, Aqyar; Greek: Σεβαστούπολη, Sevastoupoli) is a city located in the southwestern region of the Crimean Peninsula on the Black Sea. As a result of the 2014 annexation of Crimea by Russia, the city is administered as a federal city within the Crimean Federal District of the Russian Federation, though Ukraine and most of the international community continue to regard Sevastopol as a city with special status within Ukraine.
Sevastopol has a population of 393,304 (2014 Census), concentrated mostly near the Bay of Sevastopol and surrounding areas. The location and navigability of the city's harbours have made Sevastopol a strategically important port and naval base throughout history. The city has been a home to the Russian Black Sea Fleet, which is why it was considered as a separate city in Crimea of significant military importance and was therefore once a closed city.
