Paul Bigot (20 October 1870 – 8 June 1942) was a French architect.
He studied architecture at the École nationale supérieure des Beaux-Arts in Paris, in the atelier of Louis-Jules André.
It is a plaster model of about 70 square metres at a scale of 1:400, showing Rome as it would have been in the time of the emperor Constantine I (4th century AD).
The model is preserved at the University of Caen and is itself listed as an ancient monument.
Bigot was the architect of the Institut d'Art et d'Archéologie, in Paris, completed in 1932.
