Heritage lottery 2026: a Guianese mill among the 18 flagship sites
On 14 April 2026, at the Ministry of Culture, Stéphane Bern’s Mission Patrimoine unveiled the list of eighteen flagship sites selected for the ninth edition of the Loto du patrimoine, the French heritage lottery. Among them, a mill: the Loyola plantation mill, in French Guiana. It is a reminder that French milling heritage is not confined to metropolitan France, nor to village watermills.
A sugar mill, not a flour mill
The Loyola mill never ground wheat. The Loyola plantation, on the commune of Rémire-Montjoly near Cayenne, is a former sugar estate founded by the Jesuits in the 17th and 18th centuries. Its mill crushed sugar cane, before abolition and the decline of the plantation economy erased most of the estate. What remains today is a major archaeological and heritage site, studied for decades for what it reveals of how a colonial plantation was organised: the work buildings, the slave quarters, the sugar works, and this mill, whose restoration is now under way.
The presence of this mill in the 2026 flagship list says something important: the word “moulin” covers very different technical realities. The water or wind mill that produces wheat flour, and the cane mill that extracts the juice for crystallising sugar, share only the principle of the stone and of crushing. Milling heritage, in the broad sense, covers both.
How the heritage lottery works
The Loto du patrimoine, launched in 2018, rests on a simple mechanism. La Française des Jeux sells lottery tickets and scratch cards, part of whose proceeds go to the Mission Patrimoine, which redistributes them to the selected sites. Each year the selection happens at two levels: eighteen “flagship” sites, one per region, featured on the tickets, and dozens of “departmental” sites that receive more modest grants.
For the 2026 edition, the grant announced for the 102 departmental sites amounts to €21.4 million. The eighteen flagship sites enjoy strong visibility: their presence on the lottery tickets, on sale from September, guarantees them both a grant and a level of public attention that no other preservation scheme offers on this scale.
A 2026 list that casts a wide net
The 2026 selection illustrates the diversity of building types the mission defends. It includes Fort Boyard, the maritime monument made famous by the television game show, the Notre-Dame du Kreisker chapel in Saint-Pol-de-Léon, the Fosse Dionne spring in Tonnerre, the Phalsbourg synagogue, the royal manufacture of Montolieu and Fort Queyras. The Loyola plantation mill is the only mill in this flagship selection, which makes it all the more notable.
That diversity is not accidental. It signals that the notion of heritage “in peril” has broadened: no longer only churches and castles, but also industrial, agricultural and maritime sites, and vestiges of the colonial economy whose historical reading has become central. The Guianese mill ticks both of those last two boxes.
Why this also concerns flour mills
The 2026 heritage lottery did not select an industrial flour mill in the strict sense. But the parallel is instructive. Metropolitan flour mills, the cylinder-driven factories that appeared in the 19th century and replaced the stone mills, now find themselves in a situation comparable to that of rural mills thirty years ago: too numerous to all be listed, too costly to restore without help, yet central to the economic history of the cereal-growing regions.
Conversion into gîtes and housing, which this site documents, is one possible answer. Heritage lottery support is another, but it remains reserved for the most remarkable or most threatened sites. Between the two lies the whole fabric of former mills and flour mills awaiting a rehabilitation decision, for which local mobilisation remains the first lever.
