The Bastion is an impressive building of 32,000 m². It has the shape of a bastion with round towers that lead to pointed roofs. The building was expanded and renovated in 2005 by installing new wings at the rear.
The Bastion has various installations for energy management, such as its own geothermal energy storage. This underground energy storage provides heat in the winter and coolness in the summer.
The Bastion building is on the centre side of the railway, opposite the Paleiskwartier, within walking distance of the central station of the city. The centre of ‘s-Hertogenbosch is a 5-minute walk away. Via the Vughterweg the highways on the south side of the city (A2 and A65) can be reached within a few minutes.
