The Dr. Guislain Museum is, as a museum on psychiatry, a place where past and present meet. The human psyche has always been a source of fascination. But the knowledge we have now still goes hand in hand with mystery. A lot of questions remain unanswered, theories fade, but sometimes also reappear. The Dr. Guislain Museum is a lieu de mémoire and a laboratory, a museum ‘in psychiatry’ where experiment is key, where issues on metal wellbeing and illness are questioned and the complexity of the human psyche is revealed through testimonies, documents and records, art and photography.
