Casa Terme di Plinio

Set on the shore of the evocative Lago Solfatara in Fontana Liri, this extraordinary residence is one of the most unusual and captivating properties in Central Italy. Positioned directly on a small natural sulphur lake whose waters have been renowned since Roman times, the house occupies the site of the historic Terme di Plinio, an ancient thermal structure later reimagined as a remarkable private home.

Rich in atmosphere, history and natural beauty, the property enjoys an almost cinematic setting. The lake, fed by sulphur springs long appreciated for their beneficial qualities, creates a truly distinctive backdrop, while the house itself appears to emerge from the water and greenery around it. Despite this secluded and deeply scenic environment, the property lies only a short distance from the town centre.

The building, partly dating back to 1940, was originally conceived as a place where visitors could enjoy sulphur thermal baths, relax on the sun terraces and dine in the adjoining trattoria - in many ways a precursor to the modern spa concept. Over the decades it was enlarged and adapted for a number of commercial uses, including restaurant, bar and nightclub. More recently, it has been comprehensively renovated and improved, with works including upgrades to the heating system, the roof and the installation of photovoltaic panels.

The accommodation extends to approximately 456 sqm and is arranged across several levels, with the principal residential areas distributed over two main floors. One of the defining features of the house is its relationship with the lake: both the main upper floor and the lower level enjoy access to magnificent terraces, including an exceptional terrace at the lower level which sits right at the water's edge and seems almost to float above the lake.

The upper floor, extending to around 270 sqm, provides elegant and highly individual living accommodation. It includes a sitting room with fireplace opening onto the lake-facing terrace, a kitchen and dining area, a study, guest bathroom, and a bedroom wing comprising three bedrooms and two bathrooms, including a principal bedroom with en suite bathroom and its own private terrace overlooking the water.

The lower level (S1) is particularly striking as an entertaining and lifestyle space. It opens onto two terraces, one to the rear and one dramatically overlooking the lake, while another area with vehicular access can be used as parking. This floor includes a large kitchen with wood-fired oven and grill, service areas and cellar space, a spacious dining room opening onto the lakeside terrace, and a magnificent reception room with a historic 17th-century fireplace and a fully glazed façade framing the water. From here, a staircase leads to an intermediate level with a bedroom and bathroom.

The property blends residential comfort with a deeply characterful past, offering a rare combination of historic significance, natural setting and architectural drama. It would suit a buyer seeking a truly distinctive private home, but it also offers clear potential for hospitality, wellness or retreat-related use, subject to any necessary permissions.

A house of this kind is exceptionally difficult to replicate: historic, scenic, and entirely unique in its direct relationship with the sulphur lake from which it takes its identity.


LOCATION
Fontana Liri and Southern Lazio Region

Fontana Liri is one of the historic towns of the Southern Lazio region, an attractive and fertile area lying south of Rome and north of Naples, set among rolling inland hills in the heart of Italy. Historically known as a spa town, it offers a wide range of shops, services, restaurants, cafés and bars. Fontana Liri Superiore is the original medieval hilltop settlement and today forms the historic centre of Fontana Liri.

The Southern Lazio region is within easy reach of both Rome and Naples, as well as their respective airports. A day of shopping in Rome is a popular pastime, while an even shorter drive leads to the charming beaches south of the capital. Head east instead, and the mountains of the Abruzzo National Park await, with horse trekking through magnificent beech forests, as well as sparkling mountain lakes and rivers perfect for swimming during the summer months. And at the opposite end of the spectrum, while Fontana Liri itself enjoys a temperate climate, winter ski slopes can be reached in less than an hour.

Still often overlooked in favour of more widely publicised regions such as Tuscany and Umbria, the Southern Lazio region remains largely unspoilt, offering beautiful scenery, medieval hill towns and a more authentic Italian atmosphere. A home or second home in Fontana Liri, Arpino, Alatri, or in the rolling countryside that surrounds them, offers the chance to enjoy over two thousand years of history combined with an idyllic rural lifestyle. It is a place where you can still experience the "real" Italy, away from the crowds of the major tourist centres, while remaining less than ninety minutes from central Rome and Rome's airports.
