Aubonne rewards a visit made on foot. Its historic centre rises above the vineyards of La Côte, with a pale round tower marking the hilltop and Lake Geneva beyond the roofs. The name also belongs to a wider municipality: Montherod and Pizy joined Aubonne in 2021 and 2011 respectively. The Canton of Vaud counted 3,896 permanent residents in the whole commune on 31 December 2025. In the Bourg, steep lanes, civic buildings and small shops create a close-knit scale; farther out, vineyards, work areas and the wooded Aubonne valley reveal a varied corner of the Morges district.
Three settlements, one municipality
The distinction matters to visitors. Aubonne’s historic Bourg is the place for the castle silhouette, clustered houses and a walk through the old streets. Montherod and Pizy are separate village centres within the same municipal boundary, each with a more rural setting. This is not a single preserved town but a small territory with several neighbourhoods. Its daily life is also more than heritage tourism: vineyards and alpine pasture sit alongside shops, restaurants, services and a commercial and industrial area near the main road. Businesses along the old-centre route still serve residents as well as visitors, giving the Bourg a lived-in rhythm.
A castle and a town shaped together
The municipality’s history places the clustering of homes at the foot of the lords’ castle in the early twelfth century. It says people from the surrounding area, especially Trévelin, gathered there for protection. The 1234 charter known as the Franchises d’Aubonne sets out the rights and duties of the lord and Bourg residents. This is a grounded starting point for the documented story of the town.
The castle changed hands as power shifted through the region: local lords, Savoy, the lords of Grandson and the counts of Gruyère are among those named in the municipal account. In 1670 the traveller and diamond merchant Jean-Baptiste Tavernier acquired it; courtyard works of 1674–76 are associated with architect Pierre Billon and a portico of sixteen columns. Tavernier later sold the property to Henri Duquesne, a French Protestant exile. Bernese rule established a bailiwick here in 1701. From the early eighteenth century, patrician houses and a new town hall reshaped the medieval core, while the comparatively quiet centuries that followed helped preserve much of its historic fabric.
Read the streets as an open-air history
The white circular tower with its domed roof is the landmark, but Aubonne’s character lies in the sequence of spaces around it: narrow lanes, stepped houses, small courtyards and views that open toward the lake. The town hall dates from 1726–28; the Maison de Ville, once used for covered-market functions, and the Maison d’Aspre with its orangery are among the other buildings highlighted in regional heritage information. The castle is now municipal property and accommodates a secondary school and public rooms, so it is a working civic building as well as a monument. Do not assume the interiors or tower are freely open; guided visits are arranged through the local development society.
A self-guided route through the Bourg covers about 1.8 kilometres in fourteen stops. It passes shops and restaurants as well as historic façades. The route description says most of it is accessible to visitors with reduced mobility, although the old streets are not level. A guided visit takes roughly an hour and a half; allow about thirty minutes more when it includes climbing the keep. Guides can be arranged in French, German or English. Aubonne’s nickname, “Tourne-Truie,” comes with a local legend about a pig placed in a turning cage used to punish marauders. It is folklore attached to the town’s identity, not a documented account of a particular incident.
Vines, pasture and the Aubonne valley
Wine is part of the municipality’s working landscape rather than just a backdrop. Aubonne reports 7.2 hectares of vineyards cultivated by local winegrowers. The harvest is vinified by Cave de la Côte in Tolochenaz and supplies wine for local events. At a higher elevation, the municipality owns two alpine pastures near the Col du Marchairuz: Pré d’Aubonne, at 1,392 metres, and Pré de Rolle, at 1,350 metres. Their 11.5 hectares are leased for summer grazing. Cattle help maintain open land and biodiversity, a reminder that the commune extends well beyond the town above the lake.
The Aubonne valley offers a different kind of outing. Founded in 1968, the Arboretum du Vallon de l’Aubonne spreads across 200 hectares of woods and meadows. Its collections contain more than 3,000 species and varieties across over 90 genera, including four orchards devoted to old fruit varieties. The valley is also a wildlife reserve; the commune notes nearly one hundred bird species and beaver activity around the reservoir lake. Paths make it possible to choose a short woodland stroll or a longer visit among the collections. The Musée du Bois, created in 1974, interprets forestry and woodworking through tools, machines and objects. It holds more than 6,000 pieces, with around 1,500 displayed. The park is open year-round, while the museum, café and reception follow their own schedules, so check opening information before setting out.
Nearby Signal de Bougy adds family recreation and broad views over the lake and vineyards. The surrounding district has marked walks and cycling routes, while the municipal swimming pool behind the castle is a seasonal option. A visit can extend beyond the old centre: spend a morning in the Bourg, an afternoon in the valley, or combine the two at a slower pace.
Getting there and planning a visit
Aubonne has no railway station in its historic centre. A practical public-transport approach is to take a train to Allaman and continue by bus; PostBus route 720 runs between Allaman, Aubonne and Gimel. Other services link Aubonne with Rolle, Signal de Bougy, Etoy, Yens and Lavigny, depending on line and day. The municipality lists current bus and train timetables, and Allaman station has park-and-ride spaces. Check the operator’s schedule for the travel date, particularly for evenings, weekends and connections.
The seasonal Point I beside Place de l’Ancienne-Gare sells local products and provides regional visitor information; the town hall reception can help outside its opening period. Restaurants, cafés and shops are concentrated along the Bourg walk, while the Arboretum has its own visitor reception, shop and café during their opening periods. Aubonne is best approached without rushing: look back from the lanes toward the lake, then follow the road or bus into the tree-lined valley to see how its vineyard, civic and natural landscapes fit together.
