Iglesias' focal square, Piazza Quintino Sella was laid out in the 19th-century in what was at the time a field outside the city walls. It soon became a central meeting place and still today it throngs with people during the evening passeggiata (stroll). The statue in the centre commemorates Quintino Sella (of Sella e Mosca wine fame), a 19th-century statesman and champion of the area's mining industry.
