The EU, UK, Spain, and Gibraltar signed a treaty on July 14, 2026, in Brussels to end border checks at the Gibraltar-Spain land crossing, which took effect at midnight on July 15, 2026 [1, 2, 3, 4, 5]. The agreement removes the physical border fence separating Gibraltar from Spain—a barrier that had been in place since 1908 [6, 2, 7]. Thousands celebrated the lifting of controls and tearing down of the fence as the new open frontier began [6, 1, 2, 8].

Under the treaty, Gibraltar joined the Schengen Area, eliminating customs and passport checks for movement across the border [6, 1, 2, 7, 5]. Gibraltar residents can now cross into Spain using residence cards, and Spanish citizens can enter Gibraltar with government ID cards without passport stamps [3, 8]. Spain assumes responsibility for Schengen immigration controls at Gibraltar’s airport and port [2, 3].

Gibraltar has about 40,000 residents and depends heavily on 15,000 to 15,500 daily Spanish cross-border workers [1, 2, 7]. The former border controls had caused economic issues and long delays, particularly during diplomatic tensions over sovereignty claims [1, 2, 7]. Owen Smith, head of the Gibraltar Federation of Small Businesses, said a fluid border "is going to make life much easier. It’s very, very positive" [1].

The treaty safeguards Gibraltar’s British sovereignty and constitutional rights while establishing new cross-border cooperation [2]. Fabian Picardo, Gibraltar’s Chief Minister, described the frontier as a place that "has so often divided and constrained our region" but "will now become a place of cooperation and shared opportunity" [2]. Spain’s Foreign Minister José Manuel Albares said they had "put an end to a long period of discord and opened the door to a new era of coexistence for two populations that lived apart and are now joining hands, three centuries later" [2].

The agreement results from over four years of negotiations begun after the UK’s departure from the EU in 2020, when new arrangements were needed for Gibraltar’s EU ties [2, 4, 5]. Preliminary agreements to ease border issues had been reached around 2022 [3].

Following the treaty’s entry into force on July 15, Spanish Prime Minister Pedro Sanchez visited the frontier as the new arrangements took hold, with crowds crossing freely into Gibraltar [7].
