In collaboration with the PPF Foundation, Post Bellum launched a nationwide project called Let’s Not Forget 80, commemorating 80 years since the end of World War II. The PPF Foundation provided strategic partnership, financial support, and media reach, helping turn the project into one of the largest civic memory campaigns in the Czech Republic.

More than 100 cities joined the initiative, resulting in over 150 events – including exhibitions, debates, workshops, and public gatherings. The highlight was a large-scale installation on Wenceslas Square on May 8, 2025. The project connected generations, revived the stories of heroes, and opened up a public dialogue about memory, freedom, and responsibility.
