This chapter examines the complex and evolving memory culture surrounding the July 22, 2011, terrorist attacks in Norway, highlighting the interplay of collective remembrance, trauma and societal responsibility. Utilizing the concepts of “scales of memory” and Mikhail Bakhtin’s centripetal and centrifugal forces, the analysis reveals how diverse memorialization processes navigate tensions between unifying narratives and fragmented, localized interpretations. The chapter also explores Michael Rothberg’s theory of the implicated subject, emphasizing the necessity of collective reckoning with systemic conditions that foster extremism. By addressing spatial, temporal and ideological dimensions, the chapter underscores how public and private acts of memory reshape identity and responsibility in the Norwegian and global contexts. Furthermore, it calls for a nuanced, critical approach to memorialization that balances emotional, political and educational imperatives while challenging rising essentialist discourses and fostering inclusive practices of remembrance.
