During the 17th century, the estate stretched on more than 550 ha.
It belonged to the monks of Saint Jean and housed sheepfolds :
‘La Métairie de Caudéran”
During the 19th century Monsieur Mathieu SEURIN, who was a ship-owner, bought the Estate. Towards 1870, he used the existing smallholding to support new buildings: a castle, stables, an aviary, and a pigeon house. When he died – under the rule of the Pope Leon XIII, - his wife made a chapel built in Saint Mathieu which was erected in 189

Château Léognan changed owner during those years. Monsieur Jean Marie DUBOS, who was a famous wine merchant in the ‘DUBOS Frères’ company became the new landowner. He built a gallery supported by four columns. He also created a pond and a pen for fallow deers
