rom the 1870s, with the unification of Italy, the city experienced a century of rapid growth. Many outstanding buildings were erected by the end of the 18th century during the office of Mayor Ottone Bacaredda. Many of these buildings combined influences from Art Nouveau together with the traditional Sardinian taste for flower decoration: an example is the white marble City Hall near the port. Ottone Bacaredda is also famous for the violent repression of one of the earlier worker strikes in the beginning of the 20th century. Zone East of Cagliari port.During World War II Cagliari was heavily bombed by the Allies in February 1943. In order to escape from the bombardments and the misery of the destroyed town, many people left Cagliari and moved to the country or rural villages, often living with friends and relatives in overcrowded houses. This flight from the town is known as "sfollamento" (deserting). After the Italian armistice with the Allies in September 1943, the German Army took control of Cagliari and the island, but soon retreated peacefully in order to reinforce their positions in mainland Italy. The American Army then took control of Cagliari. Cagliari was strategically important during the war because of its location in the Mediterranean Sea. Many airports were near Cagliari (Elmas, Monserrato, Decimomannu, currently a NATO airbase) from which airplanes could fly to Northern Africa or mainland Italy and Sicily. After the war, the population of Cagliari rebounded and many apartment blocks were erected in new residential districts, often created with poor planning as for recreational areas.
