The Brussels stock exchange began in the early days of the 19th century, under the government of Napoleon Bonaparte, who established the first Belgian exchange – the Bourse de Fonds Publics de Bruxelles – on 13 Messidor An IX (2 July 1801). By 1858, the Bourse was flourishing under the economic and industrial boom, so the municipality of Brussels began construction of a new stock exchange on the site of the 13th-century Récollets Convent. In 1874, the inauguration ceremony was attended by King Léopold II and Queen Marie-Henriette. The ruins of the Récollets Convent have been preserved in an underground museum on the Rue de la Bourse.
