Adam explores in this article how by turning the Warsaw Uprising Mound into a public park, Archigrest and Toposcape unearth memories and histories. ‘Old Warsaw has died along with the old epoch, a new epoch and a new Warsaw are emerging,’ Gruszczyński wrote after World War II, predicting there would be ‘two Warsaws, one former and dead in the rubble of the mound, and the other alive, great, and free forever’. Although ideas for an architectural form that would express grief and remembrance started emerging in 1945, it took several decades for a site of commemoration to materialise. The project by Archigrest and Toposcape brings these stories to the surface, redefining the mound as not only a place of burial, but also the place of birth of the postwar city.
