La Nocturne des Coteaux de la Citadelle
Organised each year on the first Saturday of October, the Nocturne des Coteaux de la Citadelle extends over a site of almost 80 hectares. It aims to enhance the historical city centre (its architecture, history, etc.) and sides of the Citadelle hill through light. The festival enables the expression of the districts’ traditional open-mindedness and warmth through a event involving the inhabitants, associations and public authorities.
The 2021 and 2022 edition have been cancelled.
