The neoclassical colonnades of the former stock exchange are a reminder that this used to be a temple - albeit devoted to money. The current building, designed by Alexandre Brongniart, was opened in 1826, and since 1987 has been a venue for events, exhibitions and conferences. Since 2014, it has also been home to a conference centre and an institute of higher education for professions related to the internet, the EEMI.
