Step Inside Lisbon's Oldest Church
You feel the heat of the Alfama before you see the cathedral. The lanes climb steeply between tiled façades, and then the street opens onto Largo da Sé, where the Cathedral of Saint Mary Major — the Sé de Lisboa — stands at the top of the hill. Its two towers flank the entrance behind crenellations, and the rose window sits above the main portal. The west front looks more like a fortress than a church, a detail that dates to the Reconquista period, when the building may have served as a base during a siege. Built in 1147 on the site of the main mosque, it is the oldest church in the city.
Inside, the light comes down from the rose windows of the west façade and the transept, through the narrow windows of the side aisles, and from the lantern tower over the crossing. The nave is covered by barrel vaulting with an upper arched gallery above it. Look for the sculpted Romanesque capitals on the portals, and the iron gate in one of the chapels of the ambulatory.
Walk the Gothic Ambulatory and Find the Tombs
King Afonso IV replaced the Romanesque apse with a Gothic main chapel ringed by an ambulatory — a circular aisle of radiating chapels that survives as a key work of Portuguese Gothic. Its upper storey is covered by ribbed vaulting, and a series of clerestory windows fills the space with light. The king and his family were buried in the main chapel, but their tombs and the chapel were destroyed in the 1755 earthquake; the tombs you see there now were rebuilt in neoclassical and Rococo styles.
Three Gothic tombs from the mid-14th century stand in the ambulatory. Lopo Fernandes Pacheco, a nobleman in the service of Afonso IV, lies holding his sword, a dog at his feet. His wife Maria de Vilalobos appears over her tomb reading a Book of Hours. The third belongs to an unidentified royal princess. All three are decorated with coats-of-arms.
Near the entrance, the funerary chapel built by the merchant Bartolomeu Joanes in the early 14th century still holds his tomb with his laying figure. Machado de Castro, Portugal's foremost sculptor of the late 18th century, made the crib that stands in this Gothic chapel.
Look Down Through the Layers: The Cloister Excavations
King Dinis ordered a Gothic cloister at the end of the 13th century, and it was badly damaged by the 1755 earthquake. In the central courtyard, excavations that began in 1990 revealed a Roman road with shops on either side, part of a Roman kitchen and a sewage system, traces of later Visigoth buildings, and a section of red walls from the mosque that once stood here. In 2020 the Portuguese Minister of Culture determined that the Muslim remains should be preserved. Walking the cloister, you are standing above the city's earlier lives — Roman, Visigothic and mediaeval — laid out beneath you.
One chapter of the cathedral's story has moved elsewhere: the Saint Vincent Panels, painted by Nuno Gonçalves, are believed to have been placed in the St Vincent chapel of the ambulatory in the last quarter of the 15th century. They are now in the Museu Nacional de Arte Antiga.
Plan Your Visit Around the Hours and the Neighbourhood
The cathedral stands at Largo da Sé, 1, in Alfama, the neighbourhood east of the Baixa that survived the 1755 earthquake largely intact. From May to October it opens Monday, Tuesday, Thursday and Friday 09:30–19:00, and Wednesday and Saturday 10:00–18:00. From November to April it opens Monday to Saturday 10:00–18:00. It is closed on Sundays and Holy Days.
Because Alfama's lanes climb the hillside, you can spare your legs by taking the small historic yellow trams that serve the neighbourhood. Pair the cathedral with St. George's Castle, the other major sight in the district, and give yourself time to wander afterwards — the streets around the Sé are part of the experience.
If your visit falls in June, the Festas dos Santos fill the city with parades by day and fireworks by night, beginning with the largest fiesta for Saint Anthony on 13 June, followed by Saint John the Baptist on 23 June and Saint Peter on 28 June.
Start With the Sé
Begin your Lisbon itinerary at the top of Alfama, where the city's oldest church has absorbed earthquakes, rebuildings and centuries of change and still stands over the lanes. Check the season's opening hours, set aside a morning, and let the cathedral be your first stop before the trams and the castle pull you further up the hill.
