Few places stack 125,000 years of occupation into six square kilometres. Gibraltar runs from Gorham's Cave Neanderthals through Marinid sultans, a 1462 mosque-turned-cathedral, Trafalgar's dead and Canadian tunnelling crews — all walkable in three days.
Built above a 14th-century Merinid bathhouse, the best-preserved in Iberia, with its horseshoe arches and star-cut vents intact. Upstairs sits a cast of the 1848 Forbes' Quarry Neanderthal skull, found eight years before the Neander Valley.
The Tower of Homage was raised in 1333 for Marinid sultan Abu'l Hasan and still carries catapult-stone pockmarks from ten sieges. The Union Flag has flown from its roof since 1704; the Gatehouse and old keep gaol sit below.
Europe's last Neanderthals sheltered in these four sea caves until roughly 24,000 years ago, leaving a deliberate cross-hatch engraving cut into the bedrock. UNESCO-listed in 2016; the caves are closed, but the road platform overlooks the whole cliff.
A Moorish mosque converted into a Catholic shrine in 1462 after the Castilian reconquest, then used as a gunpowder store by the British. Sailors have prayed here for safe Strait passage for five centuries; the 15th-century wooden Madonna survived corsair raids.
Canadian and British engineers blasted some 52 km of galleries into the limestone from 1940 — enough for a 16,000-man garrison with hospital, bakery, telephone exchange and power station. Tours pass the sealed 'Stay Behind Cave' observation post.
Consecrated in 1798 as the Southport Ditch burial ground, it holds two men who died of Trafalgar wounds in 1805 alongside victims of the 1804 and 1813 yellow-fever epidemics that killed a third of the civil population.
One of only two surviving Armstrong 100-ton rifled muzzle-loaders — the twin is at Rinella in Malta — mounted in 1884 to answer Italian ironclads. The hydraulic loading machinery and shell hoist chamber are open beneath the emplacement.
A Doric arch cut directly into the 18th-century Line Wall curtain, paid for by the US Congress in 1933 to mark the American naval presence in Gibraltar during 1917-18 — a federal US monument built into a British fortification wall.
Gibraltar's Sephardi community was permitted to settle from 1729 despite the Treaty of Utrecht; this Flemish-influenced synagogue opened in 1799 after fire destroyed its predecessor. Four synagogues still serve roughly 600 Jewish residents.
Raised on the footprint of Gibraltar's principal mosque, converted for Catholic worship in 1462 and rebuilt after the 1704 bombardment and the 1779-83 siege. The Moorish courtyard survives as the patio, now open onto Main Street.
A bluff fortified since Moorish times and rebuilt in the 1860s with three 18-ton rifled muzzle-loaders behind curved Gibraltar Shield iron armour — the only surviving example of that plate type anywhere. Overlooks Rosia Bay, where Nelson's body came ashore.
Genoese fishing families settled this east-side cove in the 18th century and kept themselves apart from the garrison town. Pastel cottages, the Our Lady of Sorrows shrine and the 24 June boat-blessing survive, along with a distinct strand of Llanito.
