Paris Bourse
In 1813, at the death of Alexandre-Théodore Brongniart he presented himself successfully as candidate for completing the Paris Bourse. From 1808 to 1813 he rebuilt the cupola of the "Halle au blé", the former grain market that is the present "Bourse de commerce" of Paris. This was among the earliest uses of iron to enclose a long-span interior space.
