How is a memory territorialised through discourses and memory places? This chapter explores the territoriality of memory through the case of the Sewol Ferry Disaster, examining how a country’s sympathy for a tragic memory can be gained, lost, or become a physical place. By accessing archival records like newspapers, and conducting interviews and participation observation, the research demonstrated the evolving processes wherein ordinary spaces become territorialised, de-territorialised, and re-territorialised as memory places. The data also revealed the territorial conflicts between the “power of forgetting,” supported by the national government and right-wing supporters, and the “power of remembering,” supported by the victims’ families and liberal allies. The struggle between these two dimensions of memory politics is analysed through three sites: Gwanghwamun Square, a site of protests and counter-protests; the Danwon memorial classrooms, symbols of memory preservation; the 4.16 Life and Safety Park for commemoration. The three sites symbolise memory and serve as a reminder of the state’s irresponsibility and the loss of many young lives, materialising memory-related symbols.
