🇵🇹 Portugal · Algarve
For many people Lagos is the prettiest face of the Algarve. This city in south-west Portugal packs into a few kilometres a charming walled old centre, a lively marina and, above all, a stretch of coast of golden cliffs, sea caves and turquoise coves that takes your breath away. Its emblem is Ponta da Piedade, a headland of rock formations sculpted by the sea where boat trips slip between arches and caves that look hand-carved.
But Lagos is not only beaches. It is a city with an enormous and not always bright past. From its port, in the 15th century, the Infante Henry the Navigator drove the expeditions that opened the African route and began the age of Discovery. Here, in 1444, Europe's first African slave market was held, a chapter the city does not hide today: it tells the story soberly in a museum housed in the old market building itself. And here the earthquake and tidal wave of 1755 destroyed much of what existed, marking a before and after.
This guide takes you through the whole of Lagos: its beaches and spectacular coast — Praia Dona Ana, Praia do Camilo with its stairway of more than 200 steps, Meia Praia, Ponta da Piedade — its old centre with walls, churches and fortress, and its historical memory, which includes both the glory of the navigators and the shadow of the slave trade. We cover what to see, what each thing costs with verified figures, how to get around the Algarve without a metro, and how to use Lagos as a base for discovering the Portuguese south-west.
Lagos has roots deep in antiquity: there were settlements here that the Romans knew as Lacobriga, with an economy based on salt and the production of preserved fish and garum. Under Muslim rule, between the 8th and 13th centuries, the town — called Zawaia — was part of the al-Gharb (the Algarve). Its great moment came in the 15th century: as a naval and trading base, Lagos was the departure point for the African expeditions driven by the Infante Dom Henrique, Henry the Navigator, who lived in the city. Caravels sailed from here for the coast of Africa, and here, in 1444, Europe's first African slave market was held, when an expedition commanded by Lançarote de Freitas returned from the bay of Arguin, in present-day Mauritania, with 235 captives. Lagos was for decades the administrative capital of the Algarve and prospered on overseas trade, protected by walls reinforced in the reigns of kings João II, Manuel I and Filipe I. On 1 November 1755 the great Lisbon earthquake and the tidal wave that followed destroyed almost the entire city, including the palace where Henry the Navigator had lived, and opened a long period of decline. Lagos recovered from the mid-19th century with fish canneries and, in the 20th century, with tourism, which made it one of the Algarve's great destinations. The full story is on our history page.

Origins, formation and what the sources say.
Long before the caravels and the age of Discovery, a settlement living off the sea already stood on the south-west coast of the Iberian peninsula. Lagos traces its origins to pre-Roman peoples, and with the arrival of Rome the place became known as Lacobriga. Under Roman rule the area established itself as a productive centre tied to the Atlantic: there is evidence of salt production complexes and factories making salted fish and garum — the coveted fermented fish paste — as well as remains of pottery workshops, activity that linked Lacobriga to the trade routes of the Mediterranean and the empire.
After the fall of Rome came the Germanic peoples and, in the 8th century, the Muslim conquest, which transformed the whole south of the peninsula. The region became part of al-Gharb al-Andalus — the 'west' of al-Andalus, from which the name 'Algarve' derives — and the town, which the Arabs called Zawaia, was absorbed into that Andalusi world for several centuries. Traces of that period survive in place names, in farming and fishing techniques and in the layout of the old town.
That long phase ended in the 13th century, when the Christian Reconquest reached the far south of present-day Portugal. In the 1240s and 1250s Portuguese troops took the strongholds of the Algarve, and Lagos was absorbed into the kingdom of Portugal, which from then on added the Algarve to its crown. The town kept its seafaring and port vocation, a condition that two centuries later would place it at the centre of one of the great historical processes of the early modern age.
Lagos's great moment came in the 15th century, thanks to the Infante Dom Henrique, known as Henry the Navigator (1394-1460), son of King João I. In 1415 a Portuguese fleet set out to conquer Ceuta in North Africa, and Lagos served as a sheltered port for that armada; it was the beginning of Portuguese overseas expansion. Over the following decades, the Infante drove from the Algarve a series of expeditions that gradually worked their way down the west coast of Africa, passing the feared Cape Bojador and exploring territories until then unknown to Europeans.
Lagos became one of the main bases of that enterprise. Its port, well placed in the Atlantic south-west and close to Sagres — where tradition places the Infante's circle of navigators and cartographers — saw countless caravels leave and return. Henry the Navigator himself lived in the city, in the castle and later in a governor's palace, and under his impulse Lagos enjoyed a period of great strategic and commercial importance. The statue of the Infante that presides over today's Praça do Infante Dom Henrique recalls that founding role in the history of the Discoveries.
These expeditions opened routes that would give Portugal, in the following decades, a maritime empire stretching across Africa, Asia and America. But the 'golden age' of the Discoveries had a dark and inseparable side from the very start: alongside gold, ivory and spices, the ships also began to bring human beings captured to be sold as slaves. And that trade had its first documented European starting point in Lagos.
In 1444 Lagos was the setting for one of the most terrible episodes in European history, a fact the city does not hide today and one that deserves to be told precisely. That year an expedition of six caravels commanded by Lançarote de Freitas, organised within the African ventures sponsored by Henry the Navigator, sailed to the bay of Arguin, on the coast of present-day Mauritania. The fleet returned to Lagos with 235 people captured in Africa. In the city they were divided up and sold: it was the first market for the sale of African slaves in early modern Europe.
The chronicler Gomes Eanes de Zurara, a contemporary of the events, left a harrowing account of the landing and of the division of those people in a field outside Lagos, describing how families were separated — parents from children, husbands from wives, brothers from brothers — to be distributed among their new owners. That episode marked the beginning of Portugal's systematic participation in the Atlantic trade in human beings, a commerce that would last for centuries and tear millions of Africans from their homelands.
The building known today as the Mercado de Escravos, on the Praça do Infante — later used as a customs house — occupies the site associated with that trade and has housed, since 2016, a museum space devoted to the memory of slavery, part of the Lagos Municipal Museum. Its existence reflects an important decision: not to erase or soften this chapter but to tell it soberly and rigorously, acknowledging that the same city that was a cradle of the Discoveries was also the cradle of the slave trade in Europe. It is an essential part of the history of Lagos and of Portugal.
Through the 15th and 16th centuries Lagos enjoyed a long period of splendour. It became a prosperous port, enriched by overseas trade, and for a long time it was the administrative capital of the Algarve, the seat of regional power. To defend that wealth from piracy, from North African corsairs and from enemy fleets, the city was ringed and reinforced with walls — today a national monument — built in successive campaigns under the reigns of João II, Manuel I and Filipe I. In the 17th century the Forte da Ponta da Bandeira was added to protect the harbour entrance.
Churches, palaces and street patterns survive from that golden age, though many were transformed or destroyed by what came next. Because the history of Lagos, like that of all southern Portugal, has one date that changed everything: 1 November 1755. That morning the great Lisbon earthquake — one of the most devastating in European history — shook the whole coast. The Algarve, closer to the undersea epicentre off Cape St Vincent, was among the hardest-hit regions. The tremors were followed by a tidal wave (tsunami) that swept the shoreline.
Lagos was left virtually flattened. The sea destroyed much of the lower town, buildings, churches and fortifications collapsed, and even the palace where Henry the Navigator had lived disappeared. The years that followed brought poverty and decline: the city lost population and importance, and its status as capital of the Algarve eventually passed to Faro. Much of what you see today in the old centre dates from the rebuilding after the disaster, on the lines of the old city.
After the blow of the 1755 earthquake, Lagos took almost a century to find its rhythm again. The revival came in the mid-19th century with the canning industry: the Algarve coast, rich in sardines and tuna, filled with fish canneries that provided work and reconnected the city to the Atlantic economy. For decades, fishing and canning drove Lagos and much of the Algarve, with their trail of boats, almadravas (the traditional tuna traps) and fishing communities.
The 20th century brought the great transformation: tourism. From the 1960s onwards and, above all, after the building of Faro airport and improved transport links, the Algarve became one of Europe's great sun-and-beach destinations, very popular with British, Irish and central European visitors. Lagos, with its walled old centre, its mild climate and its spectacular coast of cliffs and sea caves — with the Ponta da Piedade as its emblem — came to live largely off visitors. The old canneries closed and the city redirected its economy towards tourism, boating and services; the building of the modern Lagos marina, in the late 20th century, symbolised that shift.
Today Lagos is one of the most visited cities in the Algarve, capable of multiplying its population in summer. Its great contemporary challenge is the one facing so many successful destinations: managing tourist pressure without losing the identity of a city with more than two thousand years of history. And that exercise includes facing all of its past: the splendour of the Discoveries and the role of Henry the Navigator, but also the memory of Europe's first slave market, which the city has chosen to preserve and explain. That balance between beauty, memory and historical honesty is perhaps what makes Lagos such a singular destination.
