Nautilus has no client and no owner. Nautilus is a passage to the river; a place to sit and read; a playground for children; a platform for talks and readings, a stage for performances, concerts, shows of various sizes. Over a summer, residents and cultural groups in Skopje welcomed an open structure at the banks of the city’s Vardar River. Conceived and realized by a group of students, TEN, and a local NGO City Creative Network (CCN), the 20-meter-long primary structure of Nautilus was constructed over the stone embankment wall, negotiating a 5-meter level change, and offering a pedestrian connection from the higher street level to the water’s edge. The threshold between road and recreational space initiates new spatial possibilities for prompting and facilitating cultural events and gatherings on this previously underutilized site. The canopy becomes a frame for the site, a projection surface, and a delineator of different spaces of transition within the otherwise rigid repeated steel structure.
