Xavier Pascal Coste, a French architect whose career spanned the nineteenth century, built an expansive portfolio through his roles as a state official and international explorer. Born in Marseille in 1787, he moved from the studio of Michel-Robert Penchaud to the École des Beaux-Arts in Paris, eventually becoming a vital link between Middle Eastern design and European public architecture.
Early Career in Egypt
Following his education in Paris, Coste established contact with the viceroy of Egypt, Muhammad Ali Pasha, in 1817. He served as the leader's personal architect and later as chief engineer for Lower Egypt. Between 1818 and 1826, he conducted extensive measurements and drawings of Cairo, which he compiled into his 1837 publication, Arabic Architecture and monuments of Cairo.

Coste’s reputation as a surveyor grew through his participation in the French embassy to the Iranian Shah. Accompanied by painter Eugène Flandin, he documented architecture across Iranian Azerbaijan, Isfahan, Shiraz, and ancient sites such as Persepolis and Pasargadae. He later returned via Baghdad, sketching ruins at Ctesiphon and Babylon before continuing his observations toward Nineveh.
Municipal Architecture in Marseille
In 1844, King Louis Philippe I appointed Coste as the chief architect of Marseille. During this tenure, he designed the Palais de la Bourse on the Canebière, commissioned by M. Luce. His work in the city included the Église Saint-Lazare, Église Saint-Joseph, Église de Saint-Barnabé, and Église de Mazargues, alongside the construction of the abattoir d'Arenc and various academic and museum buildings.
Academic and Final Years
Beyond his structural designs, Coste served as a professor of architecture at the École des Beaux-Arts and was a founding member of the Athénée intellectual centre. He remained a prolific traveler until his later years, documenting structures across Europe, including Russia and Hungary. He died in 1879 at the age of 92 and was interred at the Saint Pierre Cemetery in Marseille.
