13th-century French architects

Jean d'Orbais (ca. 1175-1231) was a French architect from Orbais-l'Abbaye, active in the Reims area. He was an architect of the High Gothic style and the first of the four architects of the Cathedral of Reims, where he is depicted in the labyrinth mosaic in the nave. He was responsible for the design of and initial work on the cathedral of Notre Dame de Reims.

Pierre de Montreuil (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), 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.

Jean (or Jehan) de Chelles (working 1258–1265) was a master mason and sculptor who was one of the architects at the Cathedral of Notre-Dame de Paris. On the exterior wall of the south transept a stone plaque is signed Johanne Magistro and dated February 1257, documenting the initiation of alterations to the transept and its portal. On his death in 1265 he was succeeded by Master Pierre de Montreuil.

Robert of Luzarches (born in Luzarches near Pontoise towards the end of the twelfth century) was a 13th-century French architect who worked on the cathedral of Notre Dame in Amiens.

Robert De Coucy or Courcy, born Reims (or Coucy, according to some authorities; died Reims in 1311) was a medieval French master-builder and son of a master-builder of the same name.

Master James of Saint George (c.–1309),(French Maitre Jacques de Saint-Georges),(Old French Mestre Jaks),(Latin Magistro Jacobo de Sancto Georgio), was a master of works/architect from Savoy, described by historian Marc Morris as "one of the greatest architects of the European Middle Ages". He was largely responsible for designing King Edward I's castles in North Wales, including Conwy, Harlech and Caernarfon (all begun in 1283) and Beaumaris on Anglesey (begun 1295).

Villard de Honnecourt (Wilars dehonecort, Vilars de Honecourt) was a 13th-century artist from Picardy in northern France. He is known to history only through a surviving portfolio or "sketchbook" containing about 250 drawings and designs of a wide variety of subjects.

Eudes de Montreuil was a 13th-century French master builder, sculptor and combat engineer. He may have died in 1289.

Pierre d'Angicourt, in French Pierre de Angicourt, in Latin Petrus de Angicuria (Angicourt, ... - active between 1269-1309) was a French architect, for about thirty years at the service of Angevin kings of the Kingdom of Naples during the second half of the thirteenth century.

Hugues Libergier (Unknown–1263) was a medieval French architect and master mason of the Gothic era who worked in Reims, France. He contributed to the Rayonnant Gothic style, and notably directed the building of the Abbey of Saint-Nicaise de Reims [fr] begun in 1231. Libergier is commemorated on a tomb slab that now resides in Reims Cathedral.
