The Passeggiata del Gianicolo follows the spine of the hill in a long, shallow curve, framed by double rows of plane trees. To the inside sit walls and villa fronts; to the outside the ground drops away and the parapet gives repeated openings over the historic centre, each bend shifting the line of domes and towers. Along the verge, marble busts mark out patriots of 1849 and the wider Risorgimento, turning the walk into a linear gallery of names and dates. You pass the junction for the ossuary, the Garibaldi monuments, the lighthouse and the emplacement for the noon cannon, all plugged into the same strip of tarmac that reads as balcony road, memorial route and viewpoint at once.
