Origin and history
La Boissière is a border stone erected in 1613 in the Jura massif, on the current municipality of Viry (the Jura department). It materializes the boundary between Franche-Comté, then under Burgundy domination, and Bugey, recently attached to the Kingdom of France after the Treaty of Lyon (1601) and confirmed by the Treaty of Auxonne (1612). This series of boundaries delimits the new political border resulting from the negotiations between France and the Savoie States.
Ranked a historic monument since 12 January 1926, this pillar bears the engraved date of 1613 and is located at the site called La Boissière. It bears witness to the territorial recompositions of the modern era, where the treaties reshaped the contours of the provinces. Its current location, although fixed, reflects geopolitical tensions between kingdoms and principalities before the administrative unification of France.
The Treaty of Auxonne (1612), less known than that of Lyon, specifies the terms of transfer of the Bugey to France, attesting the Savoyard loss of that territory. The border of La Boissière, among others, embodies this transition: on one side, Franche-Comté remains under Spanish influence (via the Habsburgs), on the other, Bugey integrates the royal domain. Its classification in the 20th century underlines its heritage importance as a vestige of the changing borders of the Old Regime.
