The Bastione di Saint Remy is the grand 19th-century staircase and terrace that connects the lower city to the Castello quarter, and it functions as Cagliari's great public outdoor room. The approach via the sweeping double staircase past triumphal arches is theatrical by design; the upper terrace, reached by this route or by a lift from the street below, offers one of the best views in the city — south over the rooftops to the bay, north toward the pale limestone walls of the citadel.
The terrace is at its best in the early evening when Cagliari comes out for the passeggiata, and it's lined with benches and the occasional food stall. In summer, temporary exhibitions and outdoor events use the space. Even without a specific event, the view and the architecture make it an essential stop on any walk through the old city.
