Chavenay can be explored through three very different aspects: Saint-Pierre Church, with its architectural and artistic history; Ferme Brillon, a community and cultural center; and a landscape shaped by the Ru de Gally and its rolling terrain. There is also a circular horse-riding route through the Plaine de Versailles, bus connections to railway stations and Versailles, and organic oils available in Chavenay. For planning your trip, local history, culture, landscape and practical transport connections all come together here.
Landscape and trails
The Ru de Gally flows through Chavenay. Together with the rolling terrain and the nearby forests of Marly and Saint-Germain, it shapes the landscape used by walkers, runners and horse riders. The river also plays a part in circular horse-riding route No. 7: known as the “Boucle Royale,” the route passes through the Plaine de Versailles and crosses the Ru de Gally several times. You will therefore encounter the same river both as part of the landscape and as a recurring point along this horse-riding route.
The route description was last updated on 1 October 2015; check current trail conditions before setting out. For travel, buses connect Chavenay with Saint-Nom-la-Bretèche railway station, the stations in Villepreux or Plaisir, and Versailles. Check current services before travelling and make sure the destinations listed match your travel or excursion plans.
Saint-Pierre Church and local history
Saint-Pierre Church has been protected as a historic monument since 7 June 1933; its main construction phase is dated to 987. Its layout can be described through several specific features: the nave comprises three bays, the choir two bays and a flat-ended apse. Load-bearing elements are made from locally sourced limestone. The walls are built partly of limestone and millstone, and partly entirely of millstone. These architectural details add a description of the building to its dating.
The furnishings also point to a different period: the 1714 altarpiece frames the painting “Les clés de Saint-Pierre.” It is a 19th-century copy of a work by Guido Reni; the original is in the Louvre. The altarpiece, the copy and the original are distinct points of reference: the church’s furnishings, the later copy of the painting and the original work. Together with the construction phase dated to 987, they offer a layered view of the church without assigning all its elements to the same period.
The washhouse is located behind Saint-Pierre Church; it was not roofed until the early 20th century. Another piece of everyday history concerns the way laundry was once done in Chavenay: first, clothes were cleaned in a washtub with ash and boiling water. The washerwomen then scrubbed and rinsed them in cold water. This sequence describes an earlier practice and adds a distinct historical perspective to the washhouse’s architectural history.
Culture and local products
Another cultural venue is Ferme Brillon. It became a community and cultural center in 1988. Performances are held in its courtyard, and it also houses the village library. Chavenay is therefore home to different cultural attractions: Saint-Pierre, with its architectural history and art, and Ferme Brillon, with its community activities, performances and library.
A specific range of products is also part of the town’s character. Ferme de Mézu produces organic oils from sunflower, soy, camelina and rapeseed, and presses and bottles its oilseed harvests on site. The oils are available in Chavenay at Epis & Pains, 5 Rue de Gally. For your plans, this is a tangible addition to the cultural and landscape attractions: a named product range featuring four different oilseeds and a local place to buy it.
