Since 1995 Peter Friedl has been photographing public playgrounds from around the world and compiling them alphabetically by reference to the names of the places. Friedl s conceptual photography project engages at a discursive level with themes of socio-history, design, and urbanism. It makes no claim to being a comprehensive typology but is instead a narrative study in which the photographed playgrounds are as important as those not shown in his photographs. This is a story of the world told through the prism of its playgrounds.  Peter Friedl adopts a comparative approach, reminiscent of the anthropological projects of the first half of the twentieth century, or at least his form of presentation suggests a kind of comparison: the quest for meaning at the intersection of repetition (image on image) and differentiation (the differences between the pictures).
