The University of Namur offers its students an exceptional learning environment thanks to its strategic location in the heart of the city. Located just a five-minute walk from the new multimodal train station, UNamur provides easy access to public transport, making it easy for students to get around every day.

Events, conferences, and activities.

At the University of Namur, we firmly believe that human dignity is inviolable and must be protected. Inspired by our Jesuit heritage, and building on our values (humanness, sustainability, freedom, excellence and openness), we are committed to creating an environment where every individual is respected, valued and celebrated.

At the University of Namur, we are firmly committed to promoting gender equality, non-discrimination and respect for diversity. Our policy is based on the values of justice, inclusion and respect for human dignity.

At the university, every student does more than attend classes: each and every one contributes to a community based on respect, solidarity and integrity. These values are essential to guarantee an environment in which to flourish to the full.This information accompanies the Student Code of Good Conduct and makes it easier to understand.

The university must set an example in terms of sustainable development in all three dimensions (economic, social, and environmental) through the way it manages its infrastructure and assets to be "sustainable in form," as well as through its commitment, as an educational and research institution, to actively contribute to environmental transition to be "sustainable in substance." All of this must be in line with the United Nations Sustainable Development Goals (SDGs).
