Is it busy? (Usually not)
The Baths of Diocletian get a fraction of the visitors of the Colosseum or the Vatican, even though they're two minutes from Termini station. On most days you walk straight to the desk. The cloister is so large, about 100 metres a side, that even a school group disappears into it.
The exceptions are the free first Sunday of the month, when every state museum in Rome fills with locals, and rainy days, when visitors staying around Termini look for somewhere indoors.

How the National Roman Museum ticket works
Because the museum is split across several buildings, the ticket is designed for hopping between them. You get one entry to each site, and you have a week from your first entry to use them.
Do you need to skip the line?
Honestly, no. There's no timed-entry system and the desk queue is normally a few minutes at most. Third-party "skip the line" tickets cost more for the same entry. What's worth doing instead:
- Buy on the official Musei Italiani portal if you want the ticket on your phone; it's linked from museonazionaleromano.it.
- Start at the Baths, then do Palazzo Massimo the same day. It's across Piazza dei Cinquecento, and the ticket's seven-day clock starts from your first entry anyway.
- Leave Palazzo Altemps for another day when you're near Piazza Navona.
- On the free first Sunday, arrive at 9 am. Free entry isn't bookable, so the line forms at the door.
What's open at the Baths right now
The Baths complex is huge and parts of it close for works and exhibition changes. At the time of writing:
- Closed until further notice: the Natatio (the great open-air swimming pool), Hall VIII, and the Museum of the Protohistory of the Latin Peoples.
- Closed for exhibition set-up: Halls X, XI and XI bis, since 9 October.
- Open: the Great Cloister, the Museum of the Written Communication of the Romans (the inscription halls), and the sculpture and jewellery displays.
Check the closures page
Closures change with little notice. Look at the news section of museonazionaleromano.it on the morning of your visit, especially if you're coming for the protohistory collection, which is shut.

A route through the Baths
1. The Great Cloister
The cloister of the Carthusian monastery built inside the baths, traditionally attributed to Michelangelo, although work started the year after his death. Its four arcades are lined with hundreds of sarcophagi, reliefs, portrait heads and capitals, and the garden in the middle has more. It's the best free-roaming space in any Rome museum; take your time.
2. The Museum of the Written Communication of the Romans
Around 10,000 Latin inscriptions: tombstones, public notices, dedications and graffiti that show how ordinary Romans recorded jobs, families, laws and prayers. It sounds dry and isn't, especially with a phone translation app.
3. Sculpture and the gold and jewellery hall
Imperial portrait busts and statues of gods, then a compact room of Roman funerary jewellery, the gold buried with the dead. Allow about 20 minutes for this section.
4. The Aula Ottagona
A separate octagonal hall of the baths, once nicknamed the "Planetarium", now home to the Museum of Rescued Art: works recovered by Italy's art-crime police. It's covered by the single ticket or costs €5 alone.
5. Santa Maria degli Angeli e dei Martiri (free)
Michelangelo turned the baths' frigidarium into this basilica for Pope Pius IV, which is why the nave is so vast and the brick front so plain. Inside, look down: a meridian line in the floor once set Rome's clocks by the sun. It has its own entrance on Piazza della Repubblica, keeps church hours and isn't part of the museum ticket.
Plans by visitor type
Arriving or leaving via Termini
With an hour to spare, the cloister and basilica are the best use of it anywhere near the station. Leave suitcases at Termini's left-luggage service first rather than dragging them round the cloister.
Ancient Rome enthusiasts
Baths in the morning, Palazzo Massimo after lunch for its frescoes and bronzes, Altemps later in the week. That's the full value of the €15.
Families
Under 18s are free. Children tend to enjoy the cloister garden and spotting animals on the sarcophagi more than the inscription halls.
Budget travellers
Come on the first Sunday for free entry, or visit only the free basilica.
Getting there
The museum entrance is at Viale Enrico de Nicola 78, facing Termini station. Termini (Metro lines A and B) and Repubblica (line A) are both under five minutes' walk, and dozens of bus routes end at Piazza dei Cinquecento.
