Its mainland is bordered to the south and east by the Mediterranean Sea except for a small land boundary with Gibraltar; to the north and northeast by France, Andorra, and the Bay of Biscay; and to the west and northwest by Portugal and the Atlantic Ocean. It is the only European country to have a border with an African country (Morocco) and its African territory accounts for nearly 5% of its population, mostly in the Canary Islands but also in Ceuta and Melilla.

A suburb is a residential area or a mixed use area, either existing as part of a city or urban area or as a separate residential community within commuting distance of a city. In most English-speaking regions, suburban areas are defined in contrast to central or inner city areas, but in Australian English and South African English, "suburb" has become largely synonymous with what is called a "neighborhood" in other countries and the term extends to inner city areas. In some areas, such as Australia, China, New Zealand, the United Kingdom, and a few U.S. states, new suburbs are routinely annexed by adjacent cities. In others, such as Arabia, Canada, France, and much of the United States, many suburbs remain separate municipalities or are governed as part of a larger local government area such as a county. The Barcelona Metro (Spanish: "Metro de Barcelona") is an unofficial brand name for an extensive network of rapid transit electrified railway lines that run mostly underground in central Barcelona and into the city's suburbs. It is part of the larger public transport system of Barcelona, the capital of Catalonia (Spain), with unified fares under the Autoritat del Transport Metropolità (ATM) scheme. As of 2014, the network is operated by two separate companies: Transports Metropolitans de Barcelona (TMB) and Ferrocarrils de la Generalitat de Catalunya (FGC). It is made up of 12 lines, combining the lines owned by the two companies. Two lines, L9 and L10 are being built at present, with both lines having different sections of each opened between 2009 and 2016. They are due to be completed in the near future.. Three lines on the network have opened as automatic train operation/driverless vehicle systems since 2009: Line 11, Line 9 and Line 10, in chronological order. Line 10 ( Zona Franca ZAL - Gorg ) is the name of one of the two branches of the Barcelona metro extension line 9 , currently under construction and to be operated by TMB . Like Line 9 and Line 11 , it will be an automatic train operation ( i.e. driverless vehicle ) metro line . London is the capital and most populous city of England and the United Kingdom, as well as the most populous city proper in the European Union. Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it "Londinium". London's ancient core, the City of London, largely retains its medieval boundaries. Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly.
