Construction of the castle, which eventually counted among the largest to be built in France, started during the second half of the 10th century under Hugh II of Lusignan. This castle was dismanteled during the 12th and then rebuilt in the 13th and again at the end of the 14th century. Lusignan was constructed in the region of Poitou, occupying a natural strongpoint, a narrow promontory that overlooked steep valleys on either side. It was already so impressive in the 12th century that a legend developed to the effect that its founder had faery aid, in the guise of the water spiritMelusine, who built it and its church through her arts, as a gift for her husband Raymondin. Lusignan at its height, just as it was in the early 15th century, is illustrated in the Très Riches Heures of Jean, duc de Berri, for whom it was a favourite residence until his death in 1416. It rises in the background of the miniature for the month of March, clearly shown in perspective, with its barbican tower at the left, the clock tower — with the exterior chute of the garderobe to its right — and the Tour Poitevine on the right, above which the gilded dragon flies, the protective spirit of Melusine. After the duc de Berri's death, Lusignan became briefly the property ofJohn, Dauphin and then passed to his brother, Charles, the futureCharles VII. First the village, then the town of Lusignan, grew up beneath the castle gates, along the slope. It formed a further enceinte when it too was later enclosed by walls. Lusignan remained a strategically important place in Poitou, in the heart of France. During the French Wars of Religion, in 1574, a plan was made of the castle's defenses; it is kept in the Bibliothèque Nationale, Paris. In the following century Lusignan was reinforced in the modern manner by Louis XIV's military architect, Vauban. Thus it was a natural structure to be used as a prison. Later it housed a school.
Destruction
The château was long used as a local quarry of pre-cut stone before it was razed by :fr:Paul Esprit Marie de La Bourdonnaye|Paul Esprit Marie de La Bourdonnaye, comte de Blossac in the 18th century, to make a pleasure ground for the town of Lusignan.
Today
What remains today are largely parts of the foundations, some built into steep hillside, part of the keep, the base of the Tour Poitevine, cisterns and cellars and remains of a subterranean passage that probably once led to the church.
