Much of today’s academic scholarship of international cultural heritage law circles around cultural heritage’s protection for the benefit of future generations. Despite this, the efforts to systematically examine the concept in more detail are scarcer. This paper seeks to fill this gap by taking a closer look at the ways in which the notion of future generations features in the body of international cultural heritage law. This contribution firstly illustrates how central the idea of protecting cultural heritage for the benefit of future generations is in international cultural heritage law. Despite this centrality, evidenced by an extensive analysis of international and regional hard and soft law, national law, case law, and policy options, its precisely contours the second argument of this paper, is that they remain elusive. Finally, skepticism is voiced over the concept’s potential ambivalent use with respect to the protection of cultural heritage.
