Guy de Gisors

Who was Guy de Gisors?

Alexandre-Jean-Baptiste-Guy de Gisors was a French architect.

His works include the Église de la Madeleine in Paris, and Saint-Vincent Cathedral in Mâcon in 1816. In about 1810 he took over the ongoing designs for the Piazza del Popolo in Rome, succeeding Giuseppe Valadier and adhering to Valadier's grand plan.

A.-J.-B.-G. de Gisors should not be confused with his relative and contemporary, French architect Jacques Pierre Gisors. Jacques Pierre worked on the Palais Bourbon in 1795, and there with Emmanuel-Chérubin Leconte designed the Salle des Cinq Cents, the Council of the Five Hundred.

Sources differ on whether the two were brothers or cousins. Sources also differ on which of the two won the Prix de Rome for architecture in 1779. fr:1778 en architecture If A.-J.-B.-G. de Gisors, he would have been age 17, not impossible for a prodigy, but Jacques Pierre would have been a far more likely age of 24.
