Historically, the territory of the estate was an independent entity reporting to the parish of Saint-Léger.Archives indicate that the seigneury of Saint-Léger and that of Fuissé were administratively linked in the XVIIᵉ century. A census dated June 22, 1647 mentions that Claude de Meaux, esquire and lieutenant for the King in the government of Mâcon, held both seigneuries simultaneously. This union is confirmed by subsequent documents, notably in 1677, when Dame Anne Bernard, widow of Claude de Meaux, took over the fiefs of Saint-Léger and Fuissé, and again in 1684, when Salomon Chesnard, heir to Anne Bernard, did the same. This situation suggests that, during this period, the two seigneuries were jointly administered, probably as a result of matrimonial alliances or acquisitions aimed at strengthening an extended seigneurial influence. At the time of the French Revolution, the estate was attached to Charnay. In 1792, the parishes of Charnay and Saint-Léger merged to form a single administrative entity under the name of Charnay-et-Saint-Léger, reflecting the site's importance in the region. Around 1800, this entity became simply Charnay, then in 1877, it adopted the name Charnay-lez-Mâcon, before becoming Charnay-lès-Mâcon in 1892, affirming its association with the neighboring town of Mâcon.

If we consider the current territorial layout, an attachment to Fuissé might seem more logical from a geographical and even organizational point of view, given the evolution of road and rail infrastructures, which reinforces the impression of greater proximity to this commune than to the center of Charnay-lès-Mâcon. However, the fact that the estate belongs to Charnay-lès-Mâcon is not the result of an arbitrary choice, but rather of a historical and administrative process that has led to its integration into a larger entity.

Located at the convergence of Charnay-lès-Mâcon, Fuissé, Solutré-Pouilly and Davayé, Domaine de Saint-Léger benefits from extensive local influence. The fact that it belongs to Charnay-lès-Mâcon has been gradually established through administrative changes. This case perfectly illustrates the specific features of communal boundaries in France, where decisions based on historical, religious and territorial criteria have endured despite territorial transformations. The attachment of Domaine de Saint-Léger to Charnay-lès-Mâcon is thus based on administrative and historical developments, which took precedence over geographical and geological considerations that might, on the face of it, have justified a more direct link with Fuissé.

The Domaine de Saint-Léger is a perfect illustration of how historical and administrative decisions have shaped today's territorial landscape. The fact that it belongs to Charnay-lès-Mâcon is the result of an ancient heritage, which has enabled its integration into a dynamic commune. Although closer to the center of other communes in the Solutré-Pouilly-Vergisson Grand Site, it retains a strong link with Charnay-lès-Mâcon, which needs to make the most of this key element of its heritage.
