Pierre de Montreuil

[2] He is one of the first named architects of 13th-century Paris, and, according to Anne Prache (writing in The Dictionary of Art), "there has been a tendency to attribute an immense role to him.

[4] He is thought to have been a master at the Basilique Saint-Denis beginning around 1247,[5] although his specific contributions are unknown,[3] and it is also generally agreed that he completed the south transept of Notre-Dame de Paris in the 1260s, after the death of Jean de Chelles.

[9] It is not known when it was begun, but its walls had only reached the bases of the windows at the time of Charles V's death in 1380, and its decoration is almost entirely of the 14th century.

[10] The refectory of the Priory of Saint-Martin-des-Champs in Paris (today the library of the Conservatoire National des Arts et Métiers) has also been attributed to Pierre de Montreuil, but without documentation; the window design probably dates to 1230–1240, that is, before Montreuil is believed to have been active.

[11] Many authors have also attributed the Chapelle Saint-Louis (built 1230–1238) at the Château de Saint-Germain-en-Laye to Montreuil.
