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. He is said to have been summoned to Paris by King Philip II who employed him in beautifying the city, and to have had a share in the work on Notre Dame de Paris. The old Amiens cathedral was destroyed by fire in 1218 and Bishop Evrard de Fouilloy had it rebuilt in Gothic style. An inscription made in 1288 in the "labyrinth" of the floor (later removed) testified that the building had begun in 1220, and names "Robert, called of Luzarches", as the architect, and as his successors, Thomas de Cormont and the latter's son. The work was completed in later centuries. Viollet-le-Duc sees a fact of great significance in
