Pierre de Montreuil (French pronunciation: [pjɛʁ də mɔ̃tʁœj]; died 17 March 1267) was a French architect. The name formerly given to him by architectural historians, Peter of Montereau (in French, Pierre de Montereau),[1] is a misnomer. It was based on his tombstone inscription Musterolo natus ("born in Musterolo"), a place name that was mistakenly identified as Montereau rather than Montreuil.[2]
