About Gibraltar

Geography and Climate

Gibraltar is a British Overseas Territory on the southern tip of the Iberian Peninsula, controlling the northern side of the Strait of Gibraltar where the Mediterranean Sea meets the Atlantic Ocean. It borders Spain by land at La Línea de la Concepción and otherwise has a Mediterranean coastline including the Bay of Gibraltar (Bay of Algeciras). The territory is dominated by the limestone Rock of Gibraltar (about 426–430 m), with narrow coastal lowlands and no permanent rivers; water needs are met primarily through desalination. The climate is Mediterranean/subtropical, with warm to hot, dry summers and mild, wetter winters, and it is strongly influenced by two prevailing winds: the humid easterly Levante and the fresher westerly Poniente. Sunshine is abundant, while frost and snow are extremely rare.

Brief History and Government

Captured by Anglo-Dutch forces in 1704 and formally ceded to Britain by the Treaty of Utrecht (1713), Gibraltar has remained under British sovereignty while developing its own democratic institutions. Officially a British Overseas Territory, it exercises extensive self-government under the 2006 Constitution: a Governor represents the UK monarch in external affairs, defence and internal security, while an elected Chief Minister and Parliament manage domestic policy. The capital and principal urban area is Gibraltar (the city itself). Key modern milestones include the 1967 sovereignty referendum and the 2006 constitutional reforms that reaffirmed self-government.

Population, Language, and Culture

Gibraltar’s usually-resident population is about 38,000 (2022 Census), reflecting sustained growth over the last decade and an ageing trend among older cohorts. English is the official language used in government and education; Spanish is widely spoken, and the local vernacular Llanito blends elements of English, Andalusian Spanish and other Mediterranean languages. Despite its small size, Gibraltar has an outsized cultural footprint, from its mixed British-Mediterranean traditions and cuisine to high-profile international events and a vibrant music and festival scene centered on Main Street and Casemates.

Economy and Currency

Gibraltar’s economy is services-led, anchored by financial services, online gaming/e-gaming, tourism and hospitality, shipping and maritime activities (including bunkering), and general trade. Government guidance and investment promotion materials highlight these sectors as core growth engines, complemented by real estate and professional services that support cross-border commerce. The legal and regulatory framework—particularly for gaming and finance—has attracted numerous international operators. The official currency is the Gibraltar pound (GIP), ISO code GIP, issued by the Government of Gibraltar and maintained at par with the British pound sterling (GBP); both GIP and GBP circulate locally.

The Postal Code System

The national postal operator is the Royal Gibraltar Post Office (RGPO). Gibraltar does not have a full multi-area postcode system like the UK; instead, the territory uses a single alphanumeric code: GX11 1AA. This code was introduced to ensure compatibility with UK and international postal infrastructure and is commonly included on inbound mail from abroad. Within Gibraltar, addressing is straightforward and may not strictly require a postcode for local delivery. A typical address places the recipient’s name, building and street, followed by “Gibraltar” and GX11 1AA (e.g., “15 Main Street, Gibraltar, GX11 1AA”). Internally, RGPO divides delivery into “walks” or districts for operational purposes, but these identifiers are not used in public addresses. Key customer services—tracking, postage calculators, and P.O. Box management—are available through RGPO’s official site.
