Castelli Romani

A short train ride southeast of Rome, the Castelli Romani scatter across the green craters of the Alban Hills: volcanic lakes, hilltop villages, papal villas, Roman ruins and wine towns that have offered the capital a cooler summer retreat for two thousand years. This is Lazio at its most sociable and its most layered.

Why visit

The Castelli Romani answer a simple Roman question: where to breathe. Sixteen towns cling to the volcanic slopes south-east of the capital, ringed by two crater lakes and a regional park, and linked by a ribbon of wineries, osterias and belvederes. The area rewards several kinds of traveller at once: archaeologists can walk the acropolis of Tusculum and the Sacred Way to Monte Cavo; art and architecture lovers have Villa Mondragone and baroque town churches; food travellers find porchetta, strawberry festivals and some of Lazio’s best-known white wines. Because everything sits within half an hour of Rome, it works equally as a day trip and as a slow touring circuit over several days.

Character and history

Volcanism made the landscape: the ancient craters of the Alban Hills now cradle Lake Albano and Lake Nemi, and their fertile soils have been farmed since the tenth century BC, when a stable settlement grew at Tusculum. The ancient Latin city became one of Rome’s noblest — Cato the Elder was born there, and Cicero wrote his Tusculan Disputations at a villa on its slopes — before being razed in 1191, its survivors scattering to the villages below. The Middle Ages and Renaissance then built what visitors see now: baronial strongholds of the Orsini, Colonna, Savelli and Aldobrandini, Renaissance villas climbing the Tuscolo hills, and the papal summer tradition that fixed the court at Castel Gandolfo. Since Roman noblemen first fled summer heat here, the Castelli have kept their vocation as Rome’s garden — cooled by altitude, fed by volcanic water, and producing a DOC wine zone whose whites lean on Malvasia and Trebbiano grapes.

What to see

Begin with antiquity at the Tusculum Archaeological Cultural Park, where acropolis walls, a theatre seating around two thousand, the forum and the paved Via dei Sepolcri lie scattered over Monte Tuscolo, still under excavation. On the slopes below, Villa Mondragone — the most monumental of the Ville Tuscolane, begun in 1573 for Cardinal Marco Sittico Altemps from designs by Martino Longhi the Elder — is called the cradle of the Gregorian calendar, for it was here that Gregory XIII worked on the reform; the villa now serves the University of Rome Tor Vergata and opens for guided tours. At Rocca di Papa, the Via Sacra (Sacred Way) of Monte Cavo climbs preserved Roman basalt towards the sanctuary of Jupiter Latiaris, spiritual centre of the ancient Latin League, while lower in the same village the Sanctuary of the Madonna del Tufo grew around a tufo stone. The towns add their own monuments: the baroque collegiate Church of Santa Maria Assunta in Cielo at Monte Compatri, the paired Church of Santa Maria Assunta and Palazzo Savelli in Rocca Priora’s historic centre, and the steep footpath climb from Lariano to the Ruins of the Rocca of Lariano on Monte Maschio d’Ariano. To the south, Velletri guards the Civic Museums of Velletri with their Volscian and Etruscan collections and the Basilica Cathedral of San Clemente I Papa e Martire, while Genzano pairs the Palazzo Sforza Cesarini and its romantic park with the neoclassical Church of Santa Maria della Cima.

How to experience

Take the area at table as much as at trail. A workable circuit: Frascati and Tusculum one day, Rocca di Papa and Monte Cavo the next, then the southern arc through Velletri, Lariano and Genzano. Time visits to the festivals — Genzano’s infiorata of flower carpets, Ariccia’s porchetta, Nemi’s strawberries — and taste the local Malvasia whites in a cantina below the villas. Hikers should save the Via Sacra for a clear morning; the park’s trails link the villages and crater rims. Trains from Rome reach Frascati and Albano, but a car unlocks the smaller hill towns and the park’s interior roads. Check opening arrangements for Villa Mondragone and the archaeological park in advance, as visits run on guided schedules rather than walk-in hours.

Practical planning

Two or three days suit the area properly; one long day can cover Frascati, Tusculum and a piazza lunch. Spring and autumn are ideal — the Castelli are busiest on Roman weekends when the weather is fine, so book restaurants. The regional park (Parco regionale dei Castelli Romani) covers the crater district; trail conditions and visitor information appear through the park and visitcastelliromani.it. Dress for churches, carry cash for small-town bars, and drive defensively on narrow hill roads. Wine tasting generally needs a reservation at the estates; porc and porchetta towns ask less of planners.
