Algarve History & Heritage Guide 2026

The history of Algarve told through its places: sites worth the detour and the context they need.

This guide covers 6+ historical sites in Algarve — Castelo de Silves, Sé Catedral de Faro (Faro Cathedral) and Fortaleza de Sagres top the list. Every recommendation carries its practical details: typical costs, the best time to visit, and what to know before you commit.

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 that shaped Algarve.

  1. 1

    Megalithic Settlement

    c. 5000 BC

    Earliest known human settlements in the Algarve; megalithic tomb complexes (dolmens) built near Alcalar, Silves and Alcoutim

  2. 2

    Phoenician Trading Posts

    c. 800 BC

    Phoenician traders establish coastal trading posts along the southern Iberian coast, particularly around Faro (Ossonoba) and Castro Marim

  3. 3

    Roman Conquest

    c. 200 BC

    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.

  4. 4

    Moorish Conquest

    AD 711

    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.

  5. 5

    Moorish Golden Age

    AD 750–1249

    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.

  6. 6

    First Christian Conquest of Silves

    1189

    King Sancho I of Portugal, aided by northern European crusaders, temporarily captures Silves. The Moors retake it in 1191.

  7. 7

    Final Reconquista of the Algarve

    1249

    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.

  8. 8

    Conquest of Ceuta — Beginnings of the Age of Discoveries

    1415

    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.

  9. 9

    Portuguese Age of Discoveries from Sagres

    1434–1488

    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.

  10. 10

    Enslaved Africans sold in Lagos

    1493

    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.

  11. 11

    Great Lisbon Earthquake

    1755

    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.

  12. 12

    Napoleonic Invasion

    1807–1811

    French forces under Junot briefly occupy the Algarve. The region suffers significant damage and economic disruption during the Peninsular War.

  13. 13

    Early Tourism Development

    1930s–1960s

    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.

  14. 14

    Carnation Revolution

    1974

    Portugal's democratic revolution ends 48 years of authoritarian rule. The Algarve votes overwhelmingly in favour of democracy. Tourism accelerates as borders open.

  15. 15

    Portugal joins the European Community

    1986

    EU membership brings substantial investment in Algarve infrastructure, motorways, the A22 Via Infante, and accelerated development of resort facilities throughout the region.
