Castel Sant’Angelo: €18 most days, €5 on the first Monday of the month

Castel Sant’Angelo is three buildings wearing each other: a Roman emperor’s tomb, a papal fortress built on top of it, and a Renaissance apartment built inside that. That history makes the choice between a ticket with recorded commentary and a tour with a live guide worth considering.

Start with the money, because it changed recently and most pages have not caught up.

What it costs officially

Full price: €18.00 since 1 July 2026.

Reduced: €2.00 for EU citizens aged 18 up to and including their 25th birthday.

Free: under-18s. Other concessions follow the Ministry of Culture’s eligibility rules. These are museum admission concessions, not a promise of free commercial tours.

That €18 is the state museum’s admission price, according to its official visitor information. Compare a reseller’s services separately.

Opening hours, and the Monday that is not closed

Tuesday to Sunday, 9 a.m. to 7.30 p.m., last entry 6.30 p.m.

Closed Mondays, and on 1 January and 25 December.

And then the exception, which is the single most useful thing on this page. Since 3 August 2026 the castle has been running “I lunedì di Castello” — extraordinary openings on the first Monday of every month, 2 p.m. to 8 p.m., last entry 7 p.m., at a flat rate of €5. The initiative runs to the end of 2026.

Two consequences, both worth planning around. If the first Monday of the month falls inside your stay, that is the day the castle costs €5 instead of €18 — and it is the only Monday you can get in at all. But tickets for those openings are sold only at the ticket office, on the day, with no reservations, so it is a turn-up-and-queue arrangement, not something you can lock in from home. On a warm evening, expect company.

For normal days, the museum recommends booking every day, especially weekends and holidays, through Musei Italiani. Tickets are named: bring an original ID matching the booking. Reservations are compulsory for school groups and groups of 10–25 people. Groups are not admitted to the special Monday openings.

What you actually walk through

The route goes up through Roman-era spaces — the helicoidal ramp that spirals through the drum of Hadrian’s tomb, and the cell that held the funerary urns — stripped of their original decoration, so what you read is the sheer engineering. Then it opens into rooms decorated in the sixteenth century with stuccoes and frescoes, which is a different building entirely and feels like it. The Giretto runs around the keep, and above that the Terrazzo dell’Angelo gives you the wide view over the city.

That view is the reason to come in the late afternoon. It faces St Peter’s, and it is the best place in Rome to look at the dome from the outside — which makes it the natural companion to, or consolation for, the dome climb.

Audio guide or guide: what each one is for

The entry with digital audio guide starts at €18 per person, with 4.6 stars from 9,390 reviews. It includes museum entry and a smartphone audio guide, in English, Polish, Portuguese, Italian, Chinese, Spanish, German and French. Bring a charged phone, headphones and ID; arrive 15 minutes early at Viale Cardinale dell’Acqua. This booking excludes wheelchair users and people with mobility impairments, and does not allow strollers. Transport, meals and tips are extra.

Other packages. Check whether an audio app, a Vatican or Pantheon visit, or a live guide is part of the selected option. A product title mentioning a combination does not make every extra part of its starting price.

The guided tour starts at €53.94 per person, lasts 1–2 hours and has 4.7 stars from 1,892 reviews. Admission and an English-speaking guide are included. Meet at the museum, Lungotevere Castello 50, and bring matching ID. It excludes wheelchair users; reaching the terrace requires stairs. Select the live-guide option when booking. A guide can connect the building’s different periods and answer questions.

The rule of thumb: if you already know roughly what Hadrian’s mausoleum was and why a pope needed a fortress attached to the Vatican, take the ticket and recording. Choose a live guide if you want to ask questions and connect the building’s different periods.

The Passetto di Borgo, and what it really costs

The Passetto is the covered corridor along the top of the wall that let popes get from the Vatican to the fortress without crossing open ground. It is the most famous thing about the castle and the most misunderstood item on every booking page.

The museum lists daytime Passetto visits on Fridays, Saturdays and Sundays, 9 a.m.–1 p.m., except the first Sunday. They include castle entry and start and finish at Castel Sant’Angelo. Saturday evening visits run within 7–11 p.m. and cover the Passetto and a specific castle route while the museum is closed. Buy the selected visit through Musei Italiani; its price and time depend on the visit type.

Crucially: the Passetto is offered through a calendar of special guided visits, including evening ones, which is being expanded over time. It is not a section you can wander into with a standard ticket, and it cannot be visited on the first Sunday of the month.

Check the complete guided-visit price in the official booking calendar for the actual daytime, evening or accessible visit; a separate admission charge is not necessarily the package total.

The route alternates two levels: the upper one open to the sky, a panoramic walk above the rooftops; the lower one covered, which is the secret corridor itself.

Stairs, lifts, and the visit that avoids them

This is where the castle is unusually well documented, and unusually good.

Work on the Passetto has made it accessible to visitors with walking difficulties, by way of two new lifts and by regrading some of the slopes along the route. The lift has an 80 cm wide opening and a cabin 120 cm wide by 125 cm deep, and takes on average 1 minute 17 seconds to reach the open level of the Passetto — the one with the view over the colonnade of St Peter’s.

Facilitated guided visits exist specifically for visitors who cannot, or would rather not, use stairs. That itinerary excludes the Bastione San Marco but covers almost the whole run of the Passetto, inside and out.

Those measurements are only part of the accessible route’s requirements. The second lift has an 80 cm entrance and a 110 × 140 cm cabin; the corridor narrows to 75 cm and has uneven flooring. Manual-wheelchair users must bring a companion, who enters free. The accessible visit starts at Torre del Mascherino; castle entry is excluded. The main museum offers only partial access to outdoor areas for visitors with disabilities.

When it is a bad idea

If you have two hours in Rome and have never seen the Colosseum, this is not where they go. If you want a quick photograph, the best one is from the bridge and costs nothing. If you are travelling with small children, the ramp and the ramparts are genuinely good — but the €18 applies to adults only, since under-18s are free, so the family arithmetic is better here than almost anywhere else in the city.

If your Rome trip includes a Monday in the rest of 2026, check the date: the first Monday opens until 8 p.m. for €5. Other Mondays are normally closed unless the museum announces a special opening.

Everything mentioned here is in our Rome selection. The same ticket-versus-guide question at the Pantheon is in the Pantheon ticket, the view you are looking at is explained in St Peter’s dome, and for where this fits in a wider plan, see which Rome tour to book.
