In 2020, the Saintonge plenary room was created on the ground floor of the Palais des Congrès. It features a 110 m² stage with the option of concealing the wings and, on the first floor, a stage balcony with railings. The theatre configuration capacity is 400 people + 7 PRM max. Can it be easily converted into a cocktail configuration for 470 people? This is possible thanks to the wheeled chairs provided by Jezet Seating. The space can be completely cleared by storing the chairs on four storage trolleys under the stage.
