Spain is a country in southwestern Europe that occupies most of the Iberian Peninsula, bordered by France and Portugal and facing both the Atlantic Ocean and the Mediterranean Sea. It is a parliamentary monarchy and a member of the European Union, with Madrid as its capital and a population of roughly 49 million people. Centuries of Roman, Visigothic, Islamic, and Christian rule have left Spain with one of the richest collections of historic architecture in Europe, from the Alhambra in Granada to Antoni Gaudi’s unfinished Sagrada Familia basilica in Barcelona.

Where Is Spain Located?

Spain sits in southwestern Europe, covering about 85 percent of the Iberian Peninsula, which it shares with Portugal. It borders Portugal to the west and France and the small state of Andorra to the northeast, across the Pyrenees. The country is bounded by the Atlantic Ocean to the west and northwest, the Cantabrian Sea along its northern coast, and the Mediterranean Sea to the east and south. Spanish territory also includes the Balearic Islands in the Mediterranean, the Canary Islands in the Atlantic off the coast of northwest Africa, and two small cities on the North African mainland, Ceuta and Melilla, which border Morocco. In total, Spain covers about 505,000 square kilometers, including roughly 12,500 square kilometers of island territory.

Geography of Spain

Spain is one of the most mountainous countries in Europe. A high interior plateau, the Meseta Central, is split by the Sistema Central and the Montes de Toledo, and ringed by peripheral ranges: the Pyrenees along the French border, the Cantabrian Mountains along the north coast, the Catalan coastal ranges in the northeast, the Sierra Morena, and the Baetic System in the south. The country’s three highest peaks are Teide (3,718 meters) on Tenerife in the Canary Islands, Mulhacen (3,478 meters) near Granada, and Aneto (3,404 meters) in the Pyrenees. The country’s major rivers, among them the Ebro, Tagus, Duero, Guadiana, and Guadalquivir, drain the plateau toward the Atlantic and Mediterranean. Spain has about 8,000 kilometers of coastline and one of the largest forested areas in continental Europe. Climate varies from continental conditions on the central plateau to a Mediterranean climate along the eastern and southern coasts, a wetter, more oceanic climate across the green north, and semi-arid conditions in parts of the southeast.

Spain’s Autonomous Communities

Spain is organized into 17 autonomous communities and 2 autonomous cities, Ceuta and Melilla, each with its own regional government and varying levels of self-rule. Three regions, Catalonia, the Basque Country, and Galicia, are sometimes described as “historic nationalities” and hold expanded autonomy, including co-official regional languages and, in the Basque Country’s case, substantial tax-raising powers.

A Brief History of Spain

Human presence on the Iberian Peninsula stretches back hundreds of thousands of years. Fossil evidence of early hominins has been found at the Atapuerca archaeological site, and Upper Paleolithic cave paintings survive at Altamira in Cantabria. Phoenician traders founded Gadir, now Cadiz, around 1100 BCE, in what is considered one of the oldest cities in Western Europe. Celtic, Carthaginian, and Roman settlement followed, and Rome controlled the peninsula, which it called Hispania, for roughly six centuries, leaving infrastructure such as the Roman theater at Merida.

After Rome’s decline, the Visigoths established a kingdom centered on Toledo. In 711, Muslim forces crossed from North Africa and within years controlled most of the peninsula, beginning nearly eight centuries of Islamic rule known as Al-Andalus, which produced monuments such as the Great Mosque of Cordoba and, later, the Alhambra palace complex in Granada. Christian kingdoms in the north gradually pushed south in a centuries-long process historians call the Reconquista. It ended in 1492, when the Catholic Monarchs, Isabella I of Castile and Ferdinand II of Aragon, captured Granada, the last Muslim stronghold on the peninsula. That same year, the Spanish crown financed Christopher Columbus’s first voyage to the Americas, opening an era of overseas empire that, under the Habsburg and later Bourbon dynasties, made Spain one of the most powerful states in the world through the 16th and 17th centuries.

Spanish power declined over the 18th and 19th centuries, and most of its American colonies had become independent by the 1820s. The 20th century brought the Spanish Civil War of 1936 to 1939 and the nearly four-decade dictatorship of General Francisco Franco, who ruled from 1939 until his death in 1975. Spain then carried out a peaceful transition to democracy, adopting a new constitution by popular referendum on December 6, 1978, which established the country as a parliamentary monarchy and devolved substantial power to newly created autonomous communities. Spain joined what is now the European Union on January 1, 1986.

Government and Economy

Spain is a parliamentary monarchy. King Felipe VI, who became head of state in 2014, holds a largely ceremonial role, while a prime minister, formally the President of the Government, leads the executive. The bicameral Cortes Generales consists of a 350-seat Congress of Deputies and a 265-seat Senate, and an independent judiciary is headed by the Supreme Court, with constitutional questions reserved for a separate Constitutional Court. Although Spain is formally a unitary state, it is highly decentralized, with the autonomous communities managing areas such as health, education, and policing. Spain joined the European Union in 1986 and has since adopted the euro and joined the Schengen passport-free travel area.

Spain’s economy had a gross domestic product of about $1.91 trillion in 2025, with GDP per capita near $38,600, according to World Bank data, making it one of the largest economies in the eurozone. Spain accounts for roughly 8.7 percent of total EU GDP. Tourism is a central part of the economy: Spain recorded a record 93.8 million international visitors in 2024, according to the national statistics institute, INE. Agriculture remains significant too; Spain is the world’s leading producer of olive oil, supplying about half of global output. Manufacturing, including automobiles and renewable energy equipment, and a large services sector round out the economy.

Culture and People

Spain’s population is just under 49 million, concentrated most heavily in and around Madrid, Barcelona, and the southern region of Andalusia. Spanish, also called Castilian, is the official language nationwide under the 1978 Constitution, while Catalan, Basque (Euskera), and Galician hold co-official status within their respective autonomous communities. Spain’s regions retain distinct culinary, musical, and architectural traditions, from Basque cuisine in the north to Andalusian flamenco in the south. Flamenco, a fusion of song, dance, and guitar playing rooted in Andalusia, was inscribed on UNESCO’s Representative List of the Intangible Cultural Heritage of Humanity in 2010.

What Is Spain Known For?

Globally, Spain is perhaps best recognized through the architecture of Antoni Gaudi, especially the still-unfinished Sagrada Familia basilica in Barcelona, one of seven Gaudi structures that together make up the UNESCO World Heritage-listed Works of Antoni Gaudi. Spain also holds 50 UNESCO World Heritage Sites, more than almost any other country, including the Alhambra, Generalife, and Albaicin in Granada and the historic centers of Toledo, Cordoba, and Santiago de Compostela. Its cultural exports extend well beyond architecture: flamenco, the running of the bulls in Pamplona, and a cuisine built around tapas, paella, and jamon iberico are internationally associated with the country, as are its football clubs, Real Madrid and FC Barcelona, two of the most widely followed sports teams in the world. Spain’s standing as a tourism destination, with a record 93.8 million visitors in 2024, reinforces this global visibility.

Catalonia and Gibraltar: Two Unresolved Territorial Questions

Spain faces two long-running territorial questions, one internal and one external, that remain genuinely contested. Within the country, the northeastern region of Catalonia has an active independence movement. In October 2017, the Catalan regional parliament held an independence referendum after Spain’s Constitutional Court had suspended the enabling law and later ruled it unconstitutional. The Catalan parliament nonetheless declared independence, and the central government responded by dissolving it and placing the region under direct rule. Several Catalan leaders were later convicted of sedition. In 2022, the UN Human Rights Committee found that Spain had violated the political rights of four of those leaders by suspending them from public office before their convictions became final. Catalan nationalists describe the matter as a question of self-determination, while the Spanish government and courts maintain that the 1978 Constitution does not permit a region to secede unilaterally; both the level of public support for independence and the legal path for any future vote remain disputed within Spain.

Separately, Gibraltar, a small peninsula on Spain’s southern coast, has been a British Overseas Territory since the 1713 Treaty of Utrecht ceded the fortress to Britain. Spain’s government maintains that sovereignty over Gibraltar should be restored to Spain, citing United Nations resolutions that it says frame the matter as one of decolonization and territorial integrity rather than self-determination. The United Kingdom and Gibraltar’s own government reject that framing and point to referendums in which Gibraltarians voted overwhelmingly to remain British. In 2025, Spain, the United Kingdom, and the European Union reached an agreement covering Gibraltar’s border, customs, and freedom of movement after Brexit, without resolving the underlying sovereignty dispute.

Why Spain Matters

Spanish is one of the six official languages of the United Nations, a reflection of the country’s historical reach across Latin America and its continuing influence through Spanish-speaking communities worldwide. As a member of the European Union, NATO, and the G20 with one of the eurozone’s larger economies, Spain plays a substantial role in European and global affairs, while its architecture, cuisine, and traditions, from the Alhambra to flamenco to Gaudi’s Barcelona, give it an outsized presence in the global cultural imagination relative to its size.
