Barcelona belongs to Spain and is the capital and largest city of the autonomous community of Catalonia in northeastern Spain. Located on the Mediterranean coast, this city is not only Spain’s second-largest city but also the political, economic, and cultural center of the Catalan region. Although Catalonia has its own language, cultural traditions, and a high degree of autonomy, in terms of international law and politics, Barcelona remains an inseparable part of the Kingdom of Spain.
Geography and Administrative Division
Barcelona is situated in the northeastern part of the Iberian Peninsula, facing the Mediterranean Sea and backed by the Collserola mountain range. Administratively, it is the capital of the autonomous community of Catalonia, which is one of Spain’s 17 autonomous communities. This system grants Catalonia significant autonomy in areas like education, healthcare, and culture, but core powers such as foreign affairs and defense remain with the Spanish central government.

Historical Background and Cultural Identity
The history of Barcelona dates back to Roman times when it was known as ‘Barcino.’ During the Middle Ages, it was a major city in the Kingdom of Aragon and later became part of a unified Spain following the union of Aragon and Castile. Notably, Catalans have always maintained a strong sense of cultural identity; they speak the Catalan language and have unique traditional festivals like Sant Jordi’s Day. This cultural distinctiveness sometimes sparks discussions about independence.

The Independence Movement and Reality
In recent years, the Catalan independence movement has garnered international attention. In 2017, the regional government of Catalonia held an independence referendum, which was declared illegal by Spain’s Constitutional Court. Although some Catalans support independence, from a legal and international recognition standpoint, Barcelona remains a part of Spanish territory, a fact widely acknowledged by the European Union and the international community.
Practical Information
For those planning to visit or live in Barcelona, it is important to know this: you will need a Spanish visa or a visa from an EU member state to enter, the currency is the Euro, and you must abide by the Spanish legal system. Barcelona’s airport code is BCN, and it is part of Spain’s aviation network. In daily life, while many locals prefer to speak Catalan, Spanish is also an official language here in Barcelona and is perfectly usable for communication.
In summary, Barcelona is a vibrant city full of cultural diversity. It belongs to Spain while maintaining its unique Catalan character. Whether it’s Gaudí’s architectural marvels, the football passion at Camp Nou, or the lively atmosphere of La Rambla, all make this city an indispensable treasure of Spain.
