The obverse of this exceptional coin shows Notre-Dame Cathedral in Paris in its purest form. Rather than contenting itself with a rectangular shape that is faithful to the structure of the building, Monnaie de Paris wanted to pay tribute to the Gothic style of the cathedral by using the contours of an ogival bay decorated with quatrefoils. Eugène Viollet-le-Duc’s reconstructed spire forms the mullion of the bay and fits in perfectly with the dynamic of the design, revealing at the top the new statue of the rooster created during the reconstruction work.
