Created in 2009 by the Friends of the Castle of Ferrette association, the ""Courtil St Fiacre"" medieval garden consists, as in the Middle Ages, of plots, each of which has a special purpose: spices, medicinal plants, vegetables or magic plants...
The layout of the garden scrupulously adheres to the information provided by the Capitulary of Charlemagne and the Plan of St Gallen.
