Collective for Historical Dialogue & Memory (CHDM) was founded by an interdisciplinary group of practitioners to contribute to memory work and the practices of interrogating, documenting, and preserving forgotten and neglected aspects of Sri Lanka’s complex past. They focus on archival work, history education, museums, and historical dialog. CHDM works in Sinhala, Tamil, and English and offers memory walks, the traveling history museum, film screenings, and human library events. Activities are free and open to the general public.
