In October 1188, he besieged Palluau, occupied by Richard The Lion Heart since 1152. The trick which allowed the fall of the fortress is the following : the attackers, penetrating in the old careers of freestone, dug an opening in the conduit of the interior well of the castle, thus condemning the defenders to capitulate or to die of thirst. 

THE TRANCHELION

In 1356, King Jean le Bon is held prisoner. The English seize several fortified towns among which Palluau. They will keep it until 1360, when they leave the place after having dismantled the castle.
It is thus the Tranchelion family that sets the foundations of the current fortress. In 1504, Charles de Tranchelion built the seignorial chapel of the church Sainte-Ménéhoulde (today Saint-Sulpice) along with two new lodgings: the East one is a little chapel, and the South one is the main lodging. 

THE BUADE DE FRONTENAC

In 1606, the castle of Palluau becomes the property of the Buade de Frontenac family.
Antoine de Buade de Frontenac (deceased in 1626) was baron then count of Palluau, Knight of the order of the Holy Spirit (highest distinction of the Monarchy), of Saint Michael, and companion of King Henri IV.
Henri de Buade de Frontenac (1596-1622) grew up with the future King Louis XIII, and became Governor of Saint-Germain-en-Laye like his father before him.
Louis de Buade de Frontenac (1620-1698), the son of Henri, was knight, count, twenty-first lord of Palluau, Isle-Savary and Tranger. He was also one of Louis XIV's counselors for both politics and military issues.
In 1672, he became Gouverneur and General Lieutenant of New France (Canada). There, he was at the head of two governments, from 1672 to 1682, and from 1689 to 1698. He died on November 28, 1698 at Saint-Louis castle in Québec. 

JEAN-BAPTISTE LOUIS FRANQUELIN

Born in 1650 at Saint-Michel de Villebernin, a township of Palluau, he accompanied the Count de Frontenac to Canada in 1672. He studied at the seminar of Québec from 1673 to 1676. He became  cartographer and  hydrographer of New France. He is the author of the first maps of North America. 

PAUL DE BEAUVILLIERS

He became the owner of Palluau in 1700. He was Pair de France, Great of Spain, Duke of Saint-Aignan and Count of Buzançais. One can still see the de Beauvilliers family's coats of arms at Saint-Laurent Priory and in the Saint-Sulpice Church.
