Château de La Bourdaisière

Château de La Bourdaisière occupies a quietly exceptional position in the Loire Valley — not for its architectural scale, though the Renaissance château is genuinely handsome, but for the unlikely combination of royal history and horticultural obsession that now defines it. Set in the soft countryside between Tours and Amboise in the Indre-et-Loire, it is a château that rewards curious visitors willing to look beyond the famous names on the Loire circuit.

The estate's royal association is with Gabrielle d'Estrées, born here around 1571 and destined to become the most influential figure in the private life of Henri IV. As the king's acknowledged favourite and the mother of three of his legitimised children — César, Alexandre, and Catherine — Gabrielle held a position at court that was effectively equivalent to queen consort. Henri's widely discussed intention to marry her was cut short by her sudden death in April 1599, before any ceremony could take place, making her story one of the more dramatically incomplete biographies attached to any Loire Valley estate. The château later passed through distinguished hands, including the Broglie family, one of France's most prominent aristocratic dynasties.

The estate's modern identity began taking shape in the 1990s, when the current owners established the National Conservatory of Tomato Varieties on the grounds — a living collection that has grown to encompass more than 700 heritage cultivars planted each summer in the kitchen garden. The conservatory is not a display or a museum but a working garden, with plants in the ground from June through October producing fruit in every imaginable colour, shape, and size: from tiny currant tomatoes scarcely larger than a pea to enormous beefsteaks, from near-black to pale gold to vivid orange-striped, from centuries-old European varieties to carefully rediscovered American heirlooms. Nothing quite prepares you for the visual strangeness of a formal French kitchen garden laid out with this kind of botanical obsession.

The exhibition inside the château traces the tomato's full history: its origins as a cultivated plant in Andean South America, its arrival in Europe via Spain in the 16th century, the long decades during which it was regarded across much of Europe with suspicion and sometimes classified as poisonous, and the eventual, irreversible culinary transformation it produced once it found its way into kitchens across the Mediterranean and beyond. The rotating displays connect botanical history with the wider story of the Columbian Exchange and what it did to European diets.

The grounds include formal parterre gardens in front of the château, the kitchen garden surrounding the conservatory, and mature trees that give the property a park-like quality unusual for a château of this scale. The building itself — rebuilt in the early 16th century during the François I era on the ruins of an earlier structure destroyed by fire — is a composed Loire Renaissance ensemble, more intimate than theatrical. For visitors already planning to visit Chenonceau, which is ten kilometres east, La Bourdaisière adds something genuinely different: a personal scale, a strange and specific seasonal spectacle, and the odd pleasure of walking through 700 tomato varieties in the garden of a woman who came within months of becoming queen of France.
