With its steamrooms and galleried courtyard, this sumptuous mansion contained all the architectural innovations of the time - private oratories in the chapel, numerous independent rooms and sculptures on the lintels describing each room. At the foot of the stair tower, the motto of Jacques Coeur is written: «À vaillans riens impossible», «To the brave, nothing is impossible». His coat of arms, made up of hearts and shells, is found all over the building.
