Roi ne suis Ne prince, ne comte aussy: Je suis le Sire de Coucy.
The Château of Pinon was originally built by Enguerrand II. of Coucy in the twelfth century. His grandfather Enguerrand I. had been invited by the Archbishop of Reims to establish himself at Pinon, which was a part of the splendid Christmas gift made by Clovis to the see of Reims, as I have already stated, after his baptism at Reims; and Enguerrand II., who appears to have been a typical baron, finding the place favourable for the feudal industry of levying toll on trade and commerce, there erected a great castle, one of the many legendary castles to be found all over Europe which boasted a window for every day in the year. He thought fit, however, to select for this castle a site which belonged to the Abbey of St.-Crispin the Great at Soissons, and thus got himself into trouble with the Church. Strong as he was, he found the Church too strong for him. The Bishop of Soissons compelled him to agree to pay an annual and perpetual rent to the Abbey, and made him also take the cross and go to the Holy Land to expiate his sacrilege. There he fell in battle. The grandson of this baron, Robert de Coucy, in 1213 granted the people of Pinon 'a right of assize according to the use and custom of Laon,' and the next year founded there a hospital. Twenty years afterwards Pinon became a commune, and John de Coucy granted the inhabitants a free market. The Château of Pinon passed in the 14th century to the elder branch of the great house of de Coucy, and in 1400 it was sold, under duress to Louis of France (Duc d'Orléans) by the last heiress of the house Marie de Coucy, daughter of Enguerrand VII. by his first wife Isabel, Princess Royal of England, and eldest daughter of Edward III. by Philippa of Hainault.
A hundred years afterwards Louis XII. had taken possession of the estates and the château, and made a gift of these to his daughter Claude de France. In spite of this, however, the property passed into the hands of the ancient family of De Lameth, and towards the end of the seventeenth century the Château de Pinon witnessed one of the most romantic and abominable murders recorded in the annals of French gallantry.
