The spatial turn in peace and conflict studies brought valuable insights about space in (post-)conflict contexts. Nevertheless, critiques of this literature call for further engagement with spatial heterogeneity. I suggest that analyzing space–time relationships is a promising avenue, as understandings of space are substantiated by heterogeneous temporal experiences. To capture space–timeheterogeneity, I introduce the concept of ‘spatio-temporal conflicts’, which draws attention to how actors construct spatial narratives based on heterogeneous and conflicting temporalities. I illustrate the analytical usefulness of this concept by employing it to explore conflicting space–time narratives around the Partisan Memorial Cemetery in post-war Mostar.
