Saint-Romain-de-Jalionas offers a range of themes for an exploratory trip: the Gallo-Roman villa of Vernai, the architectural history of Saint-Romain church, and wetlands with diverse habitats. To plan your stay, start with a simple question: should cultural history, nature, or a combination of the two shape your visit?
Vernai: Roman traces and agriculture
The remains of the Gallo-Roman villa at Vernai have been protected as a French historic monument since a decree dated June 18, 1984. The archaeological site features parts of the baths, a hydraulic mill, a grain store and the estate manager’s residence. Different parts of the former estate stand side by side, from water use to estate management.
An experimental ancient garden was created on the villa grounds in 2018. It is based on the study and practical application of treatises by Latin agronomists. Vernai thus invites visitors to look not only at building remains, but also at ancient ideas about agriculture and their practical application. Those interested in history will find two different approaches here: the surviving structures of the estate and the study of agricultural texts.
Visible, restored remains at Vernai also include the immediate surroundings of the present-day church, a thermal area and an outbuilding. The Vernai archaeological clearing lies at the edge of the Marais du Grand-Plan. This landscape setting is distinct from the separate wetland of the Marais de la Besseye.
The architectural history of Saint-Romain church
Saint-Romain church was built in the early Middle Ages, probably in the 9th or 10th century. A major renovation followed in the 19th century: in 1849, Hugues Quenin rebuilt the upper sections of the bell tower. In 1875, a new nave oriented from north to south was built according to plans and estimates by road construction inspector Collomb. Its history therefore combines an uncertain early origin with clearly dated changes from the 19th century. For a focus on cultural history, it is worth distinguishing between these two periods rather than assigning the church to just one building phase.
Wetlands and nature trails
The Marais de la Besseye is a large wetland spanning the communes of Saint-Romain-de-Jalionas and Villemoirieu. It covers 35 hectares. Its habitats include fens dominated by reeds and Cladium, alder woods and dry meadows. The area is home to plant and animal species of conservation interest. These different habitats give the site a character distinct from the archaeological sites: the focus here is on wetland landscapes and their biodiversity.
The ViaRhĂ´na cycling route runs north of Saint-Romain-de-Jalionas and is also suitable for nature walks. On the ViaRhĂ´na, before reaching Saint-Romain-de-Jalionas, take the turn-off on the right onto the Peillard path at the D 65B. This section is temporary, so it is advisable to check the current route before setting off.
Peillard and its mills
The first mill at Peillard dates back to the 13th century. The mill retains machinery from the late 19th and early 20th centuries. It opens to visitors on themed days about bread or mills, so you should not assume that it is open on a regular schedule. If visiting the mill is important to your plans, first check whether a suitable themed day is taking place.
The themes can be distinguished easily when planning your trip: Vernai and the church invite archaeological and architectural-historical exploration, while the Marais de la Besseye and the ViaRhĂ´na put nature and outdoor activities in the foreground. The Peillard mill adds the history of technology and milling to the cultural offering. When looking for a hotel in Saint-Romain-de-Jalionas, you can first decide which of these discoveries matter to your stay and plan accordingly.
