La Línea de la Concepción

La Línea de la Concepción is a Spanish city in Andalucía whose existence and purpose are defined by the neighboring British Territory of Gibraltar. The municipality sits directly on the isthmus connecting the Rock to the Spanish mainland, making it the primary land entry point for cross-border traffic and workers. This urban space developed specifically around its border position, reflecting a long and complex shared history with the British enclave. While possessing several Mediterranean and Atlantic beaches, its main role is that of a key logistical and residential support structure for the adjacent territory.
