In September, at the very beginning of autumn, a major event shakes up the country's cultural life: for one weekend, thousands of venues open their doors to the public. Visits, children's activities, concerts, shows and games are organized for the curious. The aim: to help visitors discover or rediscover thehistory and treasures of France's heritage.
The Journées du Patrimoine are the perfect time to visit some of the world's most important cultural sites, or to discover some of the most unusual and unsuspected places. Would you be tempted, for example, to visit a Parisian bank?
On September 19 and 20, 2026, the Société Générale Central Agency, based on Boulevard Haussmann in Paris, will take part in Heritage Days. The bank's headquarters hides a true architectural treasure, a monument dating from the Belle Époque. During this special weekend, the Central Agency will offer exclusive tours to admire this magnificent early 20th-century building, but also the historic bank's vault rooms.
