Gibraltar, a British Overseas Territory on Spain’s southern tip, is a rocky outcrop guarding the Mediterranean’s entrance, famed for its Rock and Barbary macaques. Its strategic port and military history draw tourists, alongside tax-free shopping and caves like St. Michael’s. A mix of British pubs and Spanish vibes, its tiny size belies its outsized role in trade and geopolitics. Gibraltar’s sovereignty remains a point of contention with Spain.
