It was called by three names which explain its history, its destination, and its architecture: "The House of the Dauphin," because Charles V., when Dauphin, had inhabited it; "The Marchandise," because it had served as town hall; and "The Pillared House" (~domus ad piloria~), because of a series of large pillars which sustained the three stories.
On l’appelait de trois noms qui expliquent son histoire, sa destination et son architecture : la Maison-au-Dauphin, parce que Charles V, dauphin, l’avait habitée ; la Marchandise, parce qu’elle servait d’Hôtel de Ville ; la Maison-aux-Piliers (domus ad piloria), à cause d’une suite de gros piliers qui soutenaient ses trois étages.
