São Jorge Castle

The hill was fortified before Rome: the first walls are dated to about 48 BC, when Lisbon became a Roman municipium, and excavations on the site have found Iron Age occupation from the 8th century BC. The Visigoths held it, and in the 10th century the Moorish rulers of al-Ushbuna rebuilt the fortifications into the citadel whose plan the present walls still follow.

The date the castle is known for is 1147. Afonso Henriques, the first king of Portugal, took Lisbon that year with a crusader army bound for the Holy Land, the one lasting success of the Second Crusade. When the capital moved from Coimbra to Lisbon in 1255 the castle became the alcáçova, the fortified royal residence, and King Dinis rebuilt it around 1300 as a palace. The dedication to Saint George came in the late 14th century, in the years of the Anglo-Portuguese alliance sealed by the marriage of João I to Philippa of Lancaster.

From 1378 the kingdom's archive sat in one of the towers, the Torre do Tombo, which today carries the name Tower of Ulysses. The palace lost its role once the Ribeira Palace was built by the river in the early 16th century, the 1531 earthquake damaged it, and the 1755 earthquake left most of the citadel in ruins apart from the walls. Barracks and later houses grew over what was left, and by the 1930s the castle had all but disappeared from the skyline.

1938 to 1940: the castle you see is a restoration

What stands on the hill now is the result of a state restoration campaign between 1938 and 1940, timed for the 1940 exhibition marking the eight hundredth anniversary of the kingdom. The later buildings were cleared, the walls and eleven towers rebuilt on the medieval footprint, and the gardens laid out on the terraces. It is a fair reconstruction rather than a survival, and the castle says so itself; the archaeological site inside the walls is where the older layers are visible in the ground.

The viewpoint terrace (Praça d'Armas)

The first thing past the gate is the wide terrace with the bronze of Afonso Henriques and the cannon along the edge. It looks south-west over the Baixa grid, the river and the Ponte 25 de Abril, with the Cristo Rei statue on the far bank. Everyone stops here first, which is why it is the most crowded part of the castle by 11:00; come back to it on the way out.

The castelejo: walls and eleven towers

The medieval castle proper sits at the north-west corner of the citadel, its highest point, a rectangle of walls with eleven towers you can walk between along the wall-walks. The stairs are steep, uneven and without handrails in places, which is the reason the castle shuts the ramparts before it shuts the gate: 17:30 in winter and, in summer, a time between 18:00 and 21:00 set by the daylight on the day. The Tower of Ulysses, the old archive tower, holds the camera obscura.

The camera obscura

A periscope in the Tower of Ulysses projects a live 360-degree image of the city onto a bowl in a darkened room, with a member of staff pointing out the landmarks. Access is only with the guided Camera Obscura tour, up to 20 minutes, included in the ticket and subject to weather; the official page prints no session times and warns that spots may be limited, so ask at the gate when you arrive rather than planning around a clock time. It is the part of the visit children remember.

The archaeological site

On the eastern side of the citadel, the excavated area shows three layers at once: Iron Age houses from the 7th century BC, the Moorish residential quarter of the 11th century, and the remains of the palace of the Counts of Santiago from the 15th to 18th centuries, destroyed in 1755. It is covered by the same ticket, but access is limited to the guided tour "Discovering the Castle" (up to one hour, included, weather permitting), so it is not a place you wander into on your own.

The permanent exhibition and the gardens

The museum in the old palace rooms shows objects found in the alcáçova, with the emphasis on the Moorish 11th and 12th centuries; from May to October the last Sunday of the month carries family activities included in the ticket; the garden terraces between the walls hold the peacocks, olive and pine trees and most of the shade, which matters in August. There is a café and a restaurant inside the walls; their hours and prices are not printed on the castle's pages we read, so treat them as an option rather than a plan.

Our route: terrace, then straight to the castelejo and the ramparts while your legs are fresh and the light is on the river, the guided Camera Obscura tour if one is running, the archaeological site with the Discovering the Castle tour, the museum, and the terrace again at the end. Ninety minutes covers it; the audio-guide e-ticket is built for exactly this loop, and the guided-introduction ticket gives you the layout in 15 minutes before you go your own way.

• Best light on the river and the bridge: the first hour after 09:00, or the last hour before the summer rampart closure
• Steepest and least protected stairs: the wall-walks of the castelejo — not for a pushchair, and unpleasant in rain
• Most shade: the garden terraces on the west side

The castle runs two timetables, read on castelodesaojorge.pt on 29 August 2026. Summer, 1 March to 31 October: 09:00 to 21:00, last admission 20:30. Winter, 1 November to the end of February: 09:00 to 18:00, last admission 17:30. It opens seven days a week and closes on only five days a year: 1 January, 1 May, 24, 25 and 31 December. One conflict to note: visitlisboa.com, the tourist board, prints the castle as open until 13:00 on 31 December, while the castle's own schedule page lists the day as closed — trust the castle, and do not plan a New Year's Eve visit.

The catch is the second timetable inside the first. Access to the wall-walks and towers closes at 17:30 in winter, and in summer at a time between 18:00 and 21:00 that the castle sets by the daylight on the day. A ticket bought at 19:30 in July may buy you the terrace and the gardens with the ramparts already roped off. If the walls are the point, be inside by 17:00 in any month.

No official page prints a busiest-hour figure. Our reading from the queue at the gate: it is shortest in the first hour after 09:00 and again in the last two hours of a summer evening, and longest from about 11:00 to 15:00 when the walking tours and the tram 28 crowd arrive together. Rain empties it, and the ramparts are slippery in rain, so that is a trade.

• Emptiest: 09:00 to 10:00 any day; a summer evening after 19:00 (terrace and gardens only once the ramparts shut)
• Busiest: 11:00 to 15:00, worst on cruise-ship days (our observation, no official count exists)
• Last practical entry for the full castle: about 16:30 in winter, about 17:00 in summer to be safe on the ramparts

Tickets are checked at the single public gate on Rua de Santa Cruz do Castelo, through the small square with the ticket office on the left. The official ticket page prints adult €17, youth 13–25 €8.50, over-65 €14, and €12 for visitors with specific needs and for culture professionals; under-12s enter free, as do Lisboa Card holders, the companion of a visitor with specific needs, and ICOM, ICOMOS, APOM and APAC card holders. A family ticket is not stated.

The castle is run by EGEAC, the Lisbon city company, not by the state museums body, so the national rule that gives Portuguese residents free Sundays does not automatically apply here and the ticket page we read on 29 August 2026 does not print a free Sunday. There is no free day for visitors from abroad at any Lisbon monument since 1 August 2024; the Lisboa Card is the only thing that makes this gate free.

The ground is cobbled and uneven everywhere, the ramparts are stairs, and the citadel is on a slope; a wheelchair user can reach the terrace and the gardens but not the wall-walks. There is no cloakroom stated. Bring water in summer; the shade is in the gardens, not on the walls.

On foot from the Baixa. From Praça da Figueira it is about 20 minutes of steady climbing by Rua da Madalena and the lanes of Mouraria or, the prettier way, by the Sé cathedral, the Santa Luzia viewpoint and the streets of Alfama, about 25 minutes. Either way the last stretch is Rua do Chão da Feira up to the gate.

Bus 737. Carris route 737 runs from Praça da Figueira to the castle gate; it is the only bus that goes to the door. Pay €2.30 (about $2.70) on board, €1.72 (about $2) with zapping credit on a navegante card, or ride free on a 24-hour €7.25 pass (about $8.50) or the Lisboa Card. The official timetable page does not print a frequency we could read, and the bus is small and fills at the terminus.

Tram 28 or 12. Neither tram reaches the castle. Both stop at Miradouro de Santa Luzia and Portas do Sol, below the walls on the south side, from where it is about eight minutes uphill on foot. The onboard tram fare is €3.30 (about $3.90), against €1.72 with zapping — the tram 28 page explains why the card matters. A tuk-tuk from the Baixa is the fourth way and the price is whatever you negotiate; none of the operators publishes a fare.

Do the castle first, at 09:00, and let the rest of the day run downhill: the lanes of Alfama and the Santa Luzia viewpoint by 11:00, the cathedral before lunch, the Baixa and the Praça do Comércio in the afternoon. That order beats the tram-28 crowd to the ramparts and gets the climbing done before the heat.

The reverse works on a winter afternoon: cathedral at 14:00, Alfama, and the castle by 16:00 for the last of the light with the ramparts still open until 17:30. In summer the ramparts may stay open past 19:00, which makes a sunset visit possible but not guaranteed; the castle decides the closing time by the daylight on the day.

On a Monday the castle is one of the few big sights that opens, while the National Pantheon and the state museums close; the Monday page lists the rest. With the Lisboa Card the castle, the bus up and the tram down are all covered, and the one-day itinerary runs this exact loop with times.
