Lisbon Port Day on a Monday: What Is Closed, What Is Open, and a Plan That Works

If your ship calls on a Monday, check your plan before you sail. The state-run museums and monuments close on Mondays, and that list includes the headline sights of Belém: the Jerónimos Monastery and Belém Tower. Plenty of passengers discover this at the monastery door after a 25-minute taxi ride.

The good news is that the core of a short port day is unaffected. The castle, the viewpoints, the old town, the cathedral, the Carmo ruins, the Oceanário and the Sintra palaces all open on Mondays, and so does the newly reopened Gulbenkian Museum. A Monday call simply means building the day around the old town rather than Belém.

Closed on Mondays

Open on Mondays

The viewpoints (Santa Luzia, Portas do Sol, Graça, Senhora do Monte), the streets of Alfama and the Baixa, and the trams have no day off at all.

The Monday bonus: the Gulbenkian

The Calouste Gulbenkian Museum reopened in July 2026 after a year and a half of renovation, and it closes on Tuesdays, not Mondays. That makes it the best major museum for a Monday call. The collection runs from ancient Egypt and Islamic art to European painting and Lalique jewellery, in a building set in one of the most restful gardens in the city.

Getting there is easy: the Blue Line runs directly from Santa Apolónia, about 10 minutes' walk from the terminal, to São Sebastião, with no change. Allow 25–30 minutes each way and at least two hours inside. Being almost entirely indoors, it is also a strong choice on a wet day.

Is Belém still worth it on a Monday?

Only in a reduced form. You can see the Jerónimos façade and cloister walls from outside, the tower from the riverside path, climb the Padrão dos Descobrimentos for the view of both, visit the MAAT, and eat custard tarts at the famous bakery next to the monastery. What you cannot do is go inside the two buildings that make Belém a World Heritage Site.

If Belém is the reason you booked the cruise, a Monday is the wrong day for it. If you are curious rather than committed, a two-hour outside-only visit works; our terminal to Belém guide covers the transport. Between October and May, the Museu de Marinha opens at 13:00 on Mondays, which fits an afternoon visit.

A Monday itinerary from the ship

This plan assumes a 09:00 start and about 7 hours ashore. Trim from the end for shorter calls, and see itineraries for 4, 6 or 8 hours for the general timing rules.

On a short call of 4–5 hours, keep only the first three steps: castle, Alfama viewpoints and the Sé, and the Baixa. All of it is within walking distance of the terminal, none of it is affected by the Monday closures, and you avoid the taxi queues that build at the terminal when a Belém plan falls apart and everyone re-plans at once.

• anchor09:00 – Castle first. Walk up through Alfama or take a taxi to Castelo de São Jorge, which opens at 09:00, before the tour groups arrive.
• anchor10:30 – Downhill through Alfama. Portas do Sol and Santa Luzia viewpoints, then the Sé on the way down.
• anchor11:45 – Baixa and Praça do Comércio. Flat walking, coffee, the arch on Rua Augusta.
• anchor12:30 – Lunch, either in the Baixa or at Time Out Market in Cais do Sodré.
• anchor14:00 – Choose one: the Carmo ruins and museum in Chiado, the Gulbenkian by metro, or the Oceanário by taxi.
• anchor15:30 – Head back. Be at the gangway at least an hour before all-aboard.

Public holidays that can affect your call

Holidays matter as much as Mondays. The state-run monuments (Jerónimos, Belém Tower, the Tile and Coach museums, the Panteão) also close on 1 January, Easter Sunday, 1 May, 13 June and 25 December, and some on 24 December. The 13 June closure is Lisbon's own city holiday, Santo António, which follows a night of street parties in Alfama. On other public holidays most sights open, but some shops close and public transport may run a reduced timetable.

Two Mondays stand out: 5 October 2026 and 1 November 2027 are both Mondays and public holidays, so expect the Monday closures plus holiday crowds at everything that is open. Carnival Tuesday (17 February 2026, 9 February 2027) is not an official holiday, but many offices close.

Opening hours change, and monuments occasionally close for events or works at short notice. Check the official site of anything that is the main reason for your day the week before you sail, and use our planner to build the rest around it.
