UK and Spain: No Shared Border, But Deep Connections

The United Kingdom does not share a land border with Spain. The UK is an island nation off northwestern Europe; Spain occupies most of the Iberian Peninsula in southwestern Europe. The English Channel and Bay of Biscay separate them — ~600 miles (965 km) from London to Madrid as the crow flies.

The One Land Border: Gibraltar

However, the UK does border Spain at Gibraltar — a 2.6 sq mi British Overseas Territory at the Mediterranean's entrance. Spain has claimed sovereignty since 1713 (Treaty of Utrecht). The border fence, opened in 1985, sees ~10,000 daily crossings — workers, shoppers, tourists.

Post-Brexit, Gibraltar's status remains negotiated. The UK and EU agreed in principle (Dec 2020) to treat Gibraltar as part of Schengen for border purposes, with Frontex guards at its port/airport — but final treaty unsigned as of 2024.
