Philip IV's treasurer was hanged on the Montfaucon gallows he had built, and the king who let him hang left legacies to his children

Enguerrand de Marigny was chamberlain to Philip IV of France. In 1313 and 1314 he ran the royal treasury and the new audit office, the chambre des comptes. The French history site Herodote says he carried out the king's coin clipping, the seizures from Lombard bankers in Paris and the trial of the Templars, whose goods went to the crown. He had the gallows at Montfaucon built to display executed criminals. Philip IV died on 29 November 1314. The king's brother, Charles of Valois, had Marigny arrested under the new king, Louis X. Twenty-eight charges were brought, including taking bribes. Marigny was refused a hearing. His accounts were found correct, and Louis was inclined only to banish him to Cyprus. Charles of Valois then accused him of sorcery. Marigny was hanged at dawn on 30 April 1315, saying he had only carried out Philip's orders, and his body was hung at Montfaucon. The 1911 Encyclopaedia Britannica says Louis X appears to have repented and left legacies to Marigny's three children, Louis, Marie and Isabelle. In 1325 Charles of Valois, dying, ordered alms given to the poor of Paris with a request to "pray for the souls of Enguerrand and Charles." Marigny had founded the collegiate church of Écouis, near Rouen, in 1313.
