As part of the Museum in Questions campaign launched in the autumn of 2021, the Royal Museums of Fine Arts of Belgium are keen to participate in the debate surrounding current social matters. Two exhibition rooms contextualise two topics for museums around the world: by shedding scientific light on the questions of colonialism and diversity, on the one hand, and the problem of the restitution of cultural goods looted during WW2, on the other, the Royal Museums aims to be a laboratory for reflection that will enable us to participate in the construction of the museum of tomorrow.
