encompasses a broad territory within which a number of discrete facilities may be located. As an examples, 1) the Russian Sevastopol Naval Base comprises individual facilities located within the city of Sevastopol proper (waterfront moorings, weapons stores, a headquarters compound, and a naval infantry base) as well as an airfield at Kacha north of the city; 2) the Leningrad Naval Base comprises all naval facilities in the greater St. Petersburg area including training schools, commissioning institutes, the naval academy, and the Kronshtadt base on Kotlin island. Overseas military base An overseas military base is a military base that is geographically located outside of the territory of the country whose armed forces are the principal occupants of the base. Such bases may be established by treaties between the governing power in the host country and another country which needs to establish the military base in the host country for various reasons, usually strategic and logistic. Furthermore, overseas military bases often serve as the source of the military brat subculture due to the children of the bases' occupant military being born or raised in the host country but raised with a remote parental knowledge of the occupant military's home country. British military bases In the 18th and 19th centuries the Royal Engineers were largely responsible for erecting military bases in the British Isles and the British Empire. In 1792 the Chief Engineer was instructed to prepare the Barrack Construction estimates for Parliament and at the same time the Department of the Barrackmaster-General was established. During the period from the 1840s through the 1860s barracks were constructed under supervision of the Royal Engineers in: Bristol (1847) Preston (1848) Tower of London (1851) Sheerness (1854) Sheffield (1854) Curragh Camp (1855) Devonport (1856) Chelsea (1861) The Cardwell Reforms (1872) ushered in another period of intensive Barrack building at Aldershot, Portsmouth, Plymouth, London, Woking, Woolwich, Dublin, Belfast, Malta, Gibraltar and the Cape of Good Hope. In 1959 the Corps' Work Services was transferred to the civilian War Department Works Organization (later renamed Property Services Agency (PSA)) and by 1965 the (Specialist Teams Royal Engineers (STRE)) were formed to plan and execute Works projects worldwide. Some British and Commonwealth naval bases are traditionally named, commissioned, and administered as though they were naval ships. For this reason they are sometimes called stone frigates.
