Jean-Charles-Léon Danjoy (31 May 1806 – 4 September 1862) was a French architect who specialized in renovating historical buildings.
[4] In 1840 Danjoy was hired by the French Historic Monuments organization, which had been created in 1837, and was given responsibility for restoring the Château de Falaise.
[4] He visited Spain in 1842, where he made a drawing of the Monastery of Benevívere, later published in a collection of lithographs of Spanish monuments.
[6] In 1843 Danjoy submitted a plan for restoration of Notre Dame de Paris in competition with Jean-Jacques Arveuf and with the winning team of Jean-Baptiste Lassus and Eugène Viollet-le-Duc.
[1] However, one of the judges of the Notre Dame competition considered that his plans paid too much attention to the religious aspects of the building and not enough to the historical.
Viollet-le-Duc praised the work that he had done in difficult circumstances in Meaux and recommended that he be decorated for his services to the arts.
Reynaud described him as an artist of the first order, with a highly developed sense of form, rich in poetic ideas that he was able to express with charm and a rare distinction.
