1147 · one city, many layers
1147, a conquest and its layers
Afonso Henriques took Lisbon on 25 October 1147 with the help of crusaders. The date marks a change of rule, not the instant creation of the city visible today. The castle hill had earlier inhabitants, and its buildings were altered again afterwards. Give the date its place, then keep looking for the layers on either side of it. A single skyline is a poor substitute for several centuries.
In short
Lisbon was conquered by Afonso Henriques with crusader help on 25 October 1147. The castle hill connects that event with earlier occupation and later rebuilding. Visit the present monument and its archaeology together; the pin on this guide is a modern location reference, not a reconstruction of the siege or its troop positions.

Roman era
Roman Olisipo, Lisbon under your feet
Roman Lisbon was Felicitas Iulia Olisipo. Its first-century theatre is still here, on the hillside at Rua de São Mamede. That changes the way we look at a walk around the cathedral: the city is not just old façades, but buildings and streets laid over earlier lives. Start with the theatre rather than trying to turn every loose stone into a Roman relic.
Still here today
The archaeological remains of a first-century theatre, interpreted by Museu de Lisboa.
Where to stand
Museu de Lisboa – Teatro Romano, Rua de São Mamede 3A. The pin is a building reference, not a verified step-free entrance.

8th century–1147
Islamic Lisbon, beyond a skyline
Islamic Lisbon is easier to understand through a house than a postcard. The castle's archaeological area preserves an eleventh- and twelfth-century residential quarter: rooms around courtyards, storage spaces and drainage. These were places to live, not just walls to defend. We would start with that domestic scale, then look across the present city. The castle silhouette alone cannot tell you which century you are seeing.
Still here today
Remains of houses, courtyards and streets in the castle's archaeological area.
Where to stand
Castelo de São Jorge. This is the public castle reference; follow the operator's arrangements for the archaeological area.

1498
Belém, voyages and the city they changed
Vasco da Gama reached Calicut in India on 20 May 1498. Belém is a useful place to follow the Lisbon end of that story, but keep the dates straight: work on Jerónimos Monastery began in 1501. The monument is part of what followed the voyages, not a building the departing fleet sailed past. Look at the stonework, then consider how trade and royal ambition could become architecture on this scale.
Still here today
Jerónimos Monastery, whose building campaign began in 1501 and was funded in part from trade revenues.
Where to stand
Jerónimos Monastery in Belém. Use the pin to find the monument; the voyage’s departure point is not plotted on this map.

1755
1755, the day the city changed
On 1 November 1755, an earthquake, tsunami and fires devastated Lisbon. At Carmo, the roofless church makes the story visible, but it is not simply a building untouched since that morning. Reconstruction began afterwards and was later abandoned; the open nave became a memorial. That is the detail we would carry into a visit: even a ruin has a history after the disaster.
Still here today
Carmo's open nave, preserved as a memorial; the museum explains its later rebuilding and the decision to leave it roofless.
Where to stand
Largo do Carmo, the public square beside the museum. Go inside the museum to see the nave; the square pin is not an admission or entrance claim.

1758
The Pombaline rebuild, street by street
The reconstruction plan approved in 1758 helped give Baixa a new order after the disaster. Manuel da Maia, Eugénio dos Santos, Carlos Mardel and the future Marquis of Pombal belong in the story, rather than one heroic name doing everything. From Praça do Comércio, look back towards the streets. Planning was about the city working again as well as how it looked, including a new drainage network below the pavement.
Still here today
Baixa's rebuilt street pattern and Praça do Comércio; the municipal history of Rua da Prata also documents the drainage system.
Where to stand
Praça do Comércio, then look north into Baixa. This is a modern square reference, not the outline of the pre-earthquake palace.

1908 / 1910
Two squares, the end of a monarchy
Two squares keep this chapter in focus. King Carlos and his heir Luís Filipe were killed at Terreiro do Paço on 1 February 1908. On 5 October 1910, José Relvas proclaimed the Republic from the City Hall balcony at Praça do Município. The places are close in the city, but the events are not the same day or the same square. Stand still for a moment and let that distinction do the work.
Still here today
The two public settings: Praça do Comércio / Terreiro do Paço and the City Hall frontage on Praça do Município.
Where to stand
Praça do Município, facing City Hall. The public square pin is for the proclamation setting, not the 1908 shooting site.

1974
25 April, freedom in the streets
On 25 April 1974, the military movement and people in the streets brought down the dictatorship. Largo do Carmo was a decisive setting: Marcelo Caetano took refuge in the barracks, surrounded by Salgueiro Maia's forces. The cheerful symbol of carnations should not flatten the day into a harmless postcard. The Aljube chronology records deaths outside the political police headquarters as well as the celebration of freedom.
Still here today
Largo do Carmo as a public setting of the revolution. The nearby church and the barracks are different buildings.
Where to stand
Largo do Carmo. Read the Aljube chronology to place the barracks and other events; the marker represents the square, not an interior visit.

1988
Chiado, rebuilt rather than replaced
A major fire struck Chiado on 25 August 1988. Álvaro Siza's reconstruction belongs to the history of the district you walk through now, not just to an architecture textbook. The lesson is different from 1755: two disasters, in different centuries, followed by different rebuilding decisions. Keep both in mind without merging them into a single story of old Lisbon burning and returning unchanged.
Still here today
Rebuilt Chiado and the Terraços do Carmo, part of the long recovery described by the municipality.
Where to stand
Chiado. The map is a neighbourhood reference, not the ignition point or a diagram of the burned area.

1998
Expo 98, a different Lisbon waterfront
Expo 98 opened on 22 May 1998 with the oceans as its theme. The fair ended, but the waterfront did not disappear with it. The Oceanário, pavilions, gardens and public spaces remain part of Parque das Nações. Come here after the older centre and the contrast is useful: Lisbon's history is not finished at the last tiled façade. The modern city deserves a chapter of its own.
Still here today
The Oceanário, former exhibition pavilions, gardens and public spaces that the parish council identifies with the Expo legacy.
Where to stand
Parque das Nações. The pin locates the present district, not the vanished exhibition ticket gates.

What survives in Lisbon today
The castle hill remains a place to read successive occupations, rather than a frozen scene from the siege.
Separate the historical event from the monument's later appearance. The castle's own archaeology and history pages make a better companion than guessing an age from a battlement.
Where to stand today
Castelo de São Jorge. The map locates the modern monument, not troop positions or a reconstructed siege boundary.
Combine the conquest story with the earlier Islamic residential remains. They belong to the same hill but answer different questions: who lived here, how they lived, and how power changed.
Read the place, not just the date
Pick one detail to look for before moving on. A historical building can combine work from several periods; an old-looking façade does not date everything behind it. The map identifies today’s public setting, while the history comes from the museum or municipal source linked here.
The photographs carry their own dates and descriptions. A painting is an artist’s view, not a measured photograph. We do not turn a neighbourhood reference into a precise entrance, or draw historical walls and shorelines from guesswork.
Make room for another chapter
Use the era selector to compare the story before and after this one. You can open a chapter on its own page, answer three questions or use the public destination link for directions. None of these actions books admission.
For a day out, choose a compact part of the city rather than racing between every pin. Belém and Parque das Nações work as separate outings. The neighbourhood and itinerary guides below help you join the historical setting to a practical Lisbon day.

Quick answers
What happened in this chapter of Lisbon history?
Afonso Henriques took Lisbon on 25 October 1147 with the help of crusaders. The date marks a change of rule, not the instant creation of the city visible today. The castle hill had earlier inhabitants, and its buildings were altered again afterwards. Give the date its place, then keep looking for the layers on either side of it. A single skyline is a poor substitute for several centuries.
What can I still see in Lisbon?
The castle hill remains a place to read successive occupations, rather than a frozen scene from the siege.
Is this a historical street map?
No. The map locates present-day places connected to the selected era. It does not reconstruct old streets, walls, coastlines, siege lines or a fire perimeter.
