The experiences of post-apartheid South Africa have often been used to open dialogue about Northern Ireland and the possible approaches to dealing with the legacy of the conflict. People in Northern Ireland have, for example, looked towards the South African Truth and Reconciliation Commission and policing in South Africa for further insights. This comparison of South Africa and Northern Ireland has now moved beyond being concerned predominantly with conflict resolution and has come to bear in the consideration of how we should present the history of the Troubles in Northern Ireland's museums and the value of preserving the built heritage of the Troubles. This paper uses the example of the 'transformation' in the South African heritage sector that came with the end of apartheid as a means to raise areas of concern that have resonance for Northern Ireland. It shows that for both Northern Ireland and South Africa it is important to think further about the impact of display, the power dynamics embedded in the construction of heritage, and the complexity of building a shared narrative from a contested past.
