Grotte di Catullo: The Roman Villa at the Tip of Sirmione

A Roman Villa, Not a Cave

The Grotte di Catullo are the remains of a grand Roman villa built between the end of the 1st century BC and the beginning of the 1st century AD, though VisitSirmione stretches construction up to the 2nd century AD. The building measured 167 by 105 m, and the archaeological area covers about two hectares at the tip of the peninsula. Italian Wikipedia calls it the most imposing Roman villa in northern Italy.

Enough of the walls stands to read the plan: terraces, a long cryptoporticus and halls facing the lake. It is assumed to have belonged to the Gens Valeria of Verona. Buy the Grotte di Catullo and museum ticket in advance and start with the museum inside the grounds, which explains what you are about to see.

Why Catullus Gets the Credit

The poet Catullus, from Verona, lived from about 84 to 54 BC, and in his poem 31 he describes coming home to his house at Sirmione (Wikipedia). The ruins, however, were built after his death, so he never lived in this building. The name comes from the 15th century, when travellers found the walls so overgrown and buried that they took them for natural caves, or grotte.

Marino Sanuto first connected the site to the poet in 1483. Isabella d'Este visited in 1514 and 1535, and the architect Andrea Palladio came to study how it was built. The link is romantic rather than factual, but the name has held for five centuries.

The Archaeological Museum

The museum opened in 1999 inside the site itself, so you pass it on the way in rather than making a separate trip. Its collection covers three layers of the peninsula: finds from the pile-dwelling settlements around the southern shore of the lake, Roman Sirmione, and the medieval period that followed. Expect mosaics, fresco fragments and Roman and Longobard artefacts.

It gives context that the bare ruins cannot, so most visitors do well to see it first. Dogs on a lead are welcome outside, but only small carried dogs may enter the museum. Start here, then walk out into the ruins.

The Great Cryptoporticus

The cryptoporticus is the signature structure of the villa, a long covered gallery running under the villa's terraces. Walking its length shows the scale of the place better than any view from outside: this was one supporting wing of a building 167 m long. The tour listing names it among the highlights along with the Giants' Hall and the Walnut Field.

The shortest accessible route through the site, suitable for visitors with reduced mobility, takes about 40 minutes by the seller's count, and the full walk takes longer. Wear shoes with grip on the old stone and gravel.

The Giants' Hall

The Giants' Hall is one of the named stops on the route through the villa, among its largest spaces. Its walls tell the later story of the site. By the 3rd century the villa had been abandoned, and part of its decoration was reused in another Roman villa in Sirmione.

In the 4th and 5th centuries its standing walls were folded into the late Roman fortifications that closed the peninsula, and burials were dug inside the ruins. General Lacombe-Saint-Michel studied the ruins in 1801 and Count Giovanni Girolamo Orti Manara published his excavations in 1856. Allow a few minutes here to take in the lake beyond.

The Olive Grove

About 1,500 olive trees grow among the ruins, of the casaliva, leccino and gargnà varieties, and the harvest resumed in 2012 after a long pause. Some of the trees are centuries old, and the grove makes the site a working farm as well as a ruin: the oil is pressed again. It is also the pleasant part of the walk in summer, because the paths through the trees hold some shade.

The site covers about two hectares, so there is room to wander. Combine the grove with the lake-view circuit at the northern tip.

The Northern Tip and the Lake View

The villa was built at the very end of the Sirmione peninsula, so the northern edge of the site drops straight to the lake with open water on three sides. This is where the panorama pays off: across the water you look toward the mountains of the upper lake, and below you the rocky shoreline runs along the base of the ruins. The 25-minute Sirmione peninsula cruise passes the Grottoes from exactly this angle, which explains why so many visitors do both.

Allow time to stand at the edge before walking back through the olive grove.

The Ministry of Culture page lists the Grotte di Catullo at Tuesday to Saturday 8:30-17:00 and Sunday 8:30-14:00, closed Mondays, 1 January and 25 December. The page does not say whether these are summer or winter hours, so check the day's hours before you set out. The table below lays out the full week.

The pattern matters for planning: a Sunday visit must happen in the morning, and no day of the week works if Monday is your only Sirmione day. Pair the ruins with the castle, which keeps the same Monday closure but opens later into the evening on other days.

Last Entry and Card-Only Payment

Last entry is 40 minutes before closing on the Ministry page, so arrive by 16:20 on weekdays and 13:20 on Sundays (our sum). Payment at the site is by card only, so bring a card rather than cash. EU citizens aged 18 to 25 pay a reduced rate at the gate, and under-18s, students and teachers with valid ID enter free.

If you want the entry sorted before you travel, the Grotte di Catullo and museum ticket costs $15 per person plus a $3.35 (€3) booking fee, is non-refundable and is valid for one day.

The shortest accessible route through the site takes about 40 minutes, and that is the baseline for a fast visit. Add the museum, the olive grove and the lake-view tip and you are closer to an hour and a half. The table below shows three ways to split your time: a short circuit of museum plus main ruins, the full site at an unhurried pace, and the ruins combined with the castle and the old town for a whole day in Sirmione.

Whichever you pick, work backwards from last entry, 40 minutes before closing.

• The villa measured 167 by 105 m, and Italian Wikipedia calls it the most imposing Roman villa in northern Italy (Wikipedia).
• The name comes from 15th century travellers who mistook the overgrown walls for caves (VisitSirmione)
• About 1,500 olive trees grow on the site and the harvest resumed in 2012 (Wikipedia)
• The building was constructed after Catullus died, so the poet never lived there (VisitSirmione)
• The state bought the whole area in 1948 after excavations began in 1939 (Wikipedia)

On Foot Through the Old Town

The site stands at the far northern tip of the narrow peninsula, beyond the Scaligero Castle gate and the whole old town, so every arrival ends on foot. The old town lies inside the ZTL, so no visitor car reaches the door. The ticket office is at Piazzale Orti Manara.

Leave time for the walk out and back through the lanes, particularly on a Sunday when last entry is 13:20 (our sum). Want the walk done for you with context? The cruise and guided walk with a drink covers the side streets with a guide.

By Car, Bus or Boat

Driving is the trap. The historic centre sits inside a summer ZTL in force from 23 March to 13 October, and driving in without authorisation brings a fine of $92.73 (€83) to $372.03 (€333). Park instead at Piazzale Monte Baldo, the main car park for the old town, or take the shuttle bus that runs from Colombare to the historic centre from April to October.

By boat, public Navigazione Laghi services dock at the pier in Piazza Carducci, and the 25-minute Sirmione peninsula cruise departs from the small harbour by the castle. See our page on getting around Lake Garda for the wider picture.

Sunday: Grottoes First

On Sunday the Grotte di Catullo shut at 14:00 with last entry by 13:20 (our sum), while the castle keeps its longer day. Walk through the old town early, reach the ruins at the 8:30 opening and give the museum the first hour, then cross to the castle after lunch. If you would rather read the ruins from the water, the 45-minute sunset tour with Prosecco runs in the evening and fits neatly after the castle.

The order is forced on Sundays, so book the morning slot and do not leave the ruins for the afternoon.

Weekdays: Castle at Opening, Grottoes Before Lunch

Tuesday to Saturday the castle opens at 8:30 with the last ticket 45 minutes before its 19:15 close, so the tower is calm early. Start there, climb the 146 steps before the heat and the crowds, then walk out to the Grotte di Catullo before lunch. For a deeper day, the 2-hour small-group cruise and guided walk with a drink adds the peninsula from the water and the quieter lanes of the town.

Keep the evening free for the lakefront, or browse the full set of Lake Garda tours if you have more days. Both sites close on Mondays, so plan around that.
