Algarve History & Heritage Guide 2025
Journey through the fascinating history and heritage sites of Algarve.
The Algarve is Portugal's southernmost district, renowned for its dramatic golden limestone cliffs, over 150 pristine beaches, and more than 300 days of sunshine per year. Stretching 155 kilometres along the Atlantic coast, this sun-drenched region blends spectacular natural scenery with charming whitewashed villages, Moorish heritage, world-class golf, and a vibrant seafood cuisine.
The Algarve takes its name from the Arabic Al-Gharb (The West), reflecting over 500 years of Moorish rule that shaped its architecture, agriculture and culture. The region was settled successively by Phoenicians, Carthaginians, Romans (who called it Lacobriga), Visigoths and finally the Moors, who cultivated the land with sophisticated irrigation systems and introduced almonds, figs and carob trees still defining the Algarvian landscape today. The Reconquista was completed in the Algarve in 1249, earlier than the rest of Portugal, and the region became a crucial launching pad for the Portuguese Age of Discoveries in the 15th century, when Sagres and Lagos served as the base for expeditions down the African coast and eventually to Brazil and India.
Historical Timeline
Key moments in Algarve's history.
Megalithic Settlement
Earliest known human settlements in the Algarve; megalithic tomb complexes (dolmens) built near Alcalar, Silves and Alcoutim
Phoenician Trading Posts
Phoenician traders establish coastal trading posts along the southern Iberian coast, particularly around Faro (Ossonoba) and Castro Marim
Roman Conquest
Romans conquer southern Iberia; major towns of Ossonoba (Faro), Lacobriga (Lagos) and Cilpes (Silves) are established. Roman fish-salting factories (cetariae) process vast quantities of tuna and mackerel.
Moorish Conquest
The Moors (Berbers and Arabs from North Africa) cross from Morocco and rapidly conquer the Iberian Peninsula. The Algarve becomes part of Al-Andalus, ruled from Silves (Xelb), the prosperous Moorish capital.
Moorish Golden Age
Silves flourishes as one of the great cities of Moorish Iberia — famous for its poetry, scholars and commerce. The Moors introduce almonds, figs, carob, citrus fruit and sophisticated irrigation systems (levadas) that still shape the Algarve landscape.
First Christian Conquest of Silves
King Sancho I of Portugal, aided by northern European crusaders, temporarily captures Silves. The Moors retake it in 1191.
Final Reconquista of the Algarve
King Afonso III completes the Reconquista of the Algarve, making it the last region in Portugal to be recaptured from the Moors. Portugal's territorial shape is essentially complete.
Conquest of Ceuta — Beginnings of the Age of Discoveries
Portuguese forces capture Ceuta in North Africa. Prince Henry the Navigator (who sets up his household at Sagres) begins his project of systematic maritime exploration.
Portuguese Age of Discoveries from Sagres
Expeditions launched from Lagos and the ports of the western Algarve progressively explore the West African coast. Bartolomeu Dias rounds the Cape of Good Hope in 1488, sailing from Lagos.
Enslaved Africans sold in Lagos
Lagos becomes the site of the first slave market in Europe (Mercado de Escravos), a dark episode in the Age of Discoveries now commemorated by the city's Slavery Museum.
Great Lisbon Earthquake
The earthquake, tsunami and subsequent fires of 1 November 1755 devastate the Algarve coast, destroying much of Faro, Lagos, Portimão and Tavira. Most of the region's historic Moorish architecture was lost in this event.
Napoleonic Invasion
French forces under Junot briefly occupy the Algarve. The region suffers significant damage and economic disruption during the Peninsular War.
Early Tourism Development
The EN125 road is completed along the southern coast. The first resort hotels are built in Portimão and Albufeira. Tourism begins to replace fishing and agriculture as the main economic driver.
Carnation Revolution
Portugal's democratic revolution ends 48 years of authoritarian rule. The Algarve votes overwhelmingly in favour of democracy. Tourism accelerates as borders open.
Portugal joins the European Community
EU membership brings substantial investment in Algarve infrastructure, motorways, the A22 Via Infante, and accelerated development of resort facilities throughout the region.
Top Historical Sites
Must-visit places for history enthusiasts.
Castelo de Silves
The finest surviving Moorish castle in Portugal, built in characteristic red sandstone with massive walls, towers and underground cisterns. The castle dominates the hilltop town of Silves and offers sweeping views over orange groves.
Sé Catedral de Faro (Faro Cathedral)
Founded in the 13th century on the site of a mosque, Faro Cathedral is a mix of Gothic, Manuerine, Renaissance and Baroque styles. The bell tower offers panoramic views over the Ria Formosa lagoon.
Fortaleza de Sagres
A vast fortification on a dramatic headland linked to Prince Henry the Navigator and the beginning of Portugal's Age of Discoveries. Features a giant stone wind rose (rosa dos ventos), Nossa Senhora da Graça chapel and sweeping Atlantic views.
Museu de Portimão
An award-winning museum housed in a beautifully restored 19th-century sardine canning factory on the Portimão waterfront. The museum tells the story of the region from Roman fish-salting to the industrial canning era with outstanding displays.
Necrópolis de Alcalar (Megalithic Tombs)
A remarkable complex of Chalcolithic (Copper Age) megalithic funerary monuments set in the countryside near Portimão, dating from 3000–2500 BC. The tholos (corbelled stone chamber) tombs are among the most impressive prehistoric monuments in southern Portugal.
Museu Municipal de Lagos (with Slavery Museum)
The Lagos Municipal Museum incorporates the site of the Mercado de Escravos — the first purpose-built slave market in Europe, established in the 1440s. A sobering and important commemoration of the darker side of the Age of Discoveries.
