What to Know About Irun
Key Facts
Irun is a municipality and city located in the province of Guipúzcoa, within the autonomous community of the Basque Country (País Vasco) in northern Spain. Situated in the comarca of Bajo Bidasoa, Irun occupies a strategic position at the westernmost point of the Pyrenees mountain range, directly on Spain's border with France. The city lies along the left bank of the Bidasoa River, which forms the natural boundary between the two countries, and is part of the Bay of Biscay's coastal region. With an approximate population of 62,000 residents, Irun covers an area of about 42.4 square kilometers, making it the second most populous municipality in Guipúzcoa after the provincial capital, San Sebastián. The municipality is administratively divided into several districts and neighborhoods, including Anaka, Behobia, Bidasoa, Olaberria, and Ventas. Irun serves as a major international transit hub due to its border location, featuring the Irun railway station—a critical link in the Madrid-Hendaye railway line—and the AP-8 motorway connecting Spain to France. Historically, the area has been inhabited since prehistoric times, with significant Roman settlements, and it played a crucial role during the Peninsular War. Today, Irun is known for its vibrant cultural scene, including the annual San Marcial festivities, and its economy is driven by logistics, commerce, and industry.
