Designed by the architect Alexandre Durville in 1912, the Casino Barrière in Trouville-sur-Mer offers slot machines, table games, a “poker room”, but also restaurants, bars and performance halls. A little history… The games were authorized in Trouville-sur-Mer from 1808 in order to offer an additional activity to rich Parisian families who came for the virtue of sea bathing. Since then, three casinos have followed one another: - The “Salon des Bains” opened in 1838 in place of the current Trouville Palace - The “Casino Salon” in 1845, built in place of the current Hôtel Flaubert. - The current casino built in 1912 was designed by the architect Durville. At that time it was considered the largest casino in France. In 1992, it became “Casino Barrière de Trouville”. Source: https://www.trouvillesurmer.org/sejourner/sortir/casino-barriere/
