Sardinia’s capital is not a beach town. It’s a CITY — 150,000 people, layers of history, a walled medieval quarter (Castello) on a hill, and a lagoon (Molentargius) where PINK FLAMINGOS live year-round, visible from the highway. Cagliari has been a port for 3,000 years — Phoenician, Carthaginian, Roman (Caralis), Pisan, Aragonese, Piedmontese, Italian. Each left buildings. The Pisans left the towers and walls (13th century). The Romans left the amphitheatre. The Aragonese left the churches. The Piedmontese left the grid streets. The flamingos were always here. Sardinia →
