Before the current Sénat, we found the Luxembourg palace raised by Mary of Medici. On this green suburb, we also found the famous château Vauvert... In the 10th century, people said that this house was a horrible haunted castle! The Devil even lived here! King Philip Augustus, when he raised the city surrounding walls, excluded the cursed castle!
King saint Louis gave it to Carthusian monks, who moved here and founded a monastery, with vast orchard and beautiful greenhouses... by the way, those greenhouses were kept after the destruction of the abbey during the Revolution, and later included in the brand new Luxembourg garden! Vauvert castle left the French expression, aller au diable Vauvert, which means “to send someone miles away”!
