The citadel in Diest is a 19th-century fort that served as an army barracks for the paratroopers until 2011. The city will renovate the citadel in several phases and repurpose it into a new city district. As part of this, part of the citadel will be given a temporary activating function from the summer of 2024. This temporary function is organised by the Citadel Diest cooperative. Here you will find a lot of entrepreneurs, organisations and associations that work on very diverse themes: work & meeting, creativity & rest, sports & games, crafts, making & learning and tasty local products. In Block 3 you will find coworking, meeting and gathering spaces, creative entrepreneurs and a wide range of activities around rest, health and well-being. Block 4 houses the makers, circular entrepreneurs and also the production and short-chain sales of local healthy food. All event spaces are located in Block 5.
