What is Sermoneta known for?

13th-century fortress, 42-meter Maschio, frescoed Camere Pinte, the seat of the Caetani for over seven hundred years. English-style garden over the ruins of a medieval town in the plain below, planted by the Caetani from the 1920s onward. Stayed at the castle during the pontificate of her father Alexander VI; the family of Pope Boniface VIII held the town for centuries.

When is the best time to visit Sermoneta?

Apr–Oct. April through June and September through October are when Sermoneta sits at its best. The Lepini spur catches a breeze the Pontine Plain below never gets in summer. April and May are also the months to see the Giardino di Ninfa in flower; the garden opens only on selected weekends from April to early November. July and August are hot in the plain and only slightly cooler at 257 meters; the castle is the coolest place in town. Winter is quiet, with the castle on a reduced visitor schedule. The Via Francigena del Sud passes through; pilgrims walk the lower town all year.

Sermoneta is a comune in the province of Latina, Lazio region of Italy, about 13 kilometers from Latina.

Why come

Sermoneta sits on a spur of the Monti Lepini, above what was once the Pontine Marshes and is now reclaimed plain. The Annibaldi held the site in the 13th century until 1297, when Pietro Caetani, nephew of Pope Boniface VIII, bought it and made it the seat of one of the great medieval Roman families. The walled village climbs from the Porta Annibaldi up through narrow lanes to the fortress at its head, the two parts of the town, lower gate and upper stronghold, built as one continuous piece of Caetani-era stone.

Below, in the valley, the family later turned an abandoned settlement into a garden, so the plain that emptied of people in the 17th century became, in the 20th, a cultivated ruin looked after by the same family that once ruled the hill above it. The town on the spur and the garden in the plain are the same story told at two elevations: a family that built to hold ground in the medieval centuries, then returned centuries later to plant over what the land had reclaimed.

What to see

Castello Caetani
The Maschio tower stands beside the smaller Maschietto, and the Camere Pinte hold their frescoes from the 1470s. Charles V lodged here in April 1536 with 1,000 knights and 4,000 infantry.
Giardino di Ninfa
The garden grows over stone that was once a working medieval town, abandoned in the 17th century after malaria emptied the plain; walls and a former church line survive among the planting.
Cattedrale di Santa Maria Assunta
Romanesque collegiate church from the 13th century inside the walls, with a 14th-century panel of the Madonna by Benozzo Gozzoli.
Centro storico
Walled medieval village inside Caetani-era stonework, narrow lanes climbing from the Porta Annibaldi up to the castle.
Sinagoga (Ghetto)
Former Jewish quarter and synagogue from the 13th century in the lower part of the village, used until the community's expulsion in 1555.
