With a population of 1.6 million within city limits, its urban area extends to numerous neighbouring municipalities within the Province of Barcelona and is home to around 4.8 million people, making it the sixth most populous urban area in the European Union after Paris, London, Madrid, the Ruhr area and Milan. It is one of the largest metropolises on the Mediterranean Sea, located on the coast between the mouths of the rivers Llobregat and Besòs, and bounded to the west by the Serra de Collserola mountain range, the tallest peak of which is 512 metres (1,680 feet) high.

Founded as a Roman city, in the Middle Ages Barcelona became the capital of the County of Barcelona. After merging with the Kingdom of Aragon, Barcelona continued to be an important city in the Crown of Aragon as an economic and administrative centre of this Crown and the capital of the Principality of Catalonia. Barcelona has a rich cultural heritage and is today an important cultural centre and a major tourist destination. Particularly renowned are the architectural works of Antoni Gaudí and Lluís Domènech i Montaner, which have been designated UNESCO World Heritage Sites. The headquarters of the Union for the Mediterranean are located in Barcelona. The city is known for hosting the 1992 Summer Olympics as well as world-class conferences and expositions and also many international sport tournaments.

Barcelona is one of the world's leading tourist, economic, trade fair and cultural centres, and its influence in commerce, education, entertainment, media, fashion, science, and the arts all contribute to its status as one of the world's major global cities. It is a major cultural and economic centre in southwestern Europe, 24th in the world (before Zürich, after Frankfurt) and a financial centre. In 2008 it was the fourth most economically powerful city by GDP in the European Union and 35th in the world with GDP amounting to €177 billion. In 2012 Barcelona had a GDP of $170 billion; and it was leading Spain in employment rate in that moment.

In 2009 the city was ranked Europe's third and one of the world's most successful as a city brand. In the same year the city was ranked Europe's fourth best city for business and fastest improving European city, with growth improved by 17% per year, and the city has been experiencing strong and renewed growth for the past three years. Since 2011 Barcelona has been a leading smart city in Europe. Barcelona is a transport hub, with the Port of Barcelona being one of Europe's principal seaports and busiest European passenger port, an international airport, Barcelona–El Prat Airport, which handles over 50 million passengers per year, an extensive motorway network, and a high-speed rail line with a link to France and the rest of Europe.

Bridgetown is the capital and largest city of Barbados. Formerly The Town of Saint Michael, the Greater Bridgetown area is located within the parish of Saint Michael. Bridgetown is sometimes locally referred to as "The City", but the most common reference is simply "Town". As of 2014, its metropolitan population stands at roughly 110,000.

The Bridgetown port, found along Carlisle Bay (at 13.106°N 59.632°W) lies on the southwestern coast of the island. Parts of the Greater Bridgetown area (as roughly defined by the Ring Road Bypass or more commonly known as the ABC Highway), sit close to the borders of the neighbouring parishes Christ Church and St. James. The Grantley Adams International Airport for Barbados, is located 16 kilometres (10 mi) southeast of Bridgetown city centre, and has daily flights to major cities in the United Kingdom, United States, Canada and the Caribbean. There is no longer a local municipal government, but it is a constituency of the national Parliament. During the short-lived 1950s-1960s Federation of the British West Indian Territories, Bridgetown was one of three capital cities within the region being considered to be the Federal capital of region.

The present-day location of the city was established by English settlers in 1628; a previous settlement under the authority of Sir William Courten was at St. James Town. Bridgetown is a major West Indies tourist destination, and the city acts as an important financial, informatics, convention centre, and cruise ship port of call in the Caribbean region. On 25 June 2011, "Historic Bridgetown and its Garrison" was added as a World Heritage Site of UNESCO.
