Laurent-Benoît Dewez

He is considered the most influential architect in the Austrian Netherlands (present-day Belgium) from the second half of the 18th century. His architectural projects are of international stature and introduced a neoclassical style, with Italian and English influences, to the region. He designed a large number of châteaux, abbeys and churches in Belgium, many of which were damaged after the French Revolution.

The field of work recorded is architecture. Works named in the authority record are Heylissem Abbey, Basilique Notre-Dame de Bonne-Espérance, Vlierbeek Abbey, Castle of Seneffe, Gembloux Abbey and Saint Begga Collegiate Church. Distinctions recorded are Boursier de la fondation Lambert Darchis.

Dewez was born in Petit-Rechain near Verviers on 14 April 1731. The abbot of the Abbey of Saint Hubert sent him on a study trip to Italy. There he worked with Luigi Vanvitelli and came into contact with Robert Adam, Giovanni Battista Piranesi, Johann Joachim Winckelmann and Charles-Louis Clérisseau. After a subsequent study trip to Split in the company of Robert Adam he worked briefly as an associate of the Adam brothers in London in 1758. In 1759 he came back to the Austrian Netherlands to start the rebuilding of Abbaye Notre-Dame d'Orval, a work which was never completed.

In 1767 he was appointed court architect to the Governor of the Austrian Netherlands, Charles-Alexandre de Lorraine for whom he reconstructed the Château of Mariemont, which was demolished in the aftermath of the French Revolution. A masterpiece still preserved today is the Château de Seneffe built between 1763 and 1768. His last great project was the new State Prison in Vilvoorde. Dewez's adversaries, envious of his success as court architect, accused him of failures and fraud in the execution of this project. Due to these accusations, he fell into disfavour and was dismissed as court architect. On the invasion of the Austrian Netherlands by French revolutionary troops in 1793, Dewez fled to Prague. In the Czech capital, he designed and built some private mansions for the local bourgeoisie. In 1804 he returned to Belgium. He died relatively impoverished in Groot-Bijgaarden on 1 November 1812. His tombstone with a brief Latin description of his life and work, can still be seen in the exterior wall of the church of Groot-Bijgaarden.
