[4]The Metropolitan City of Cagliari extends over the southern part of the Campidano plain, between two mountain ranges.

The Metropolitan City of Cagliari has a Mediterranean climate with hot, dry Summers and mild Winters.

[7] Whilst the Italian government challenged the law,[8] thus stalling its implementation,[9] on March 12, 2022, the Constitutional Court ruled in favor of the Autonomous Region of Sardinia.

According to Eurostat in 2009 the metropolitan area of Cagliari had a per capita purchasing power standard (PPS) of 21.699 euros, which is 92.4% of the European Union (27) data.

[14] The traditional economy was based on agriculture: the cultivation of wheat, olive groves and vineyards, gardens and orchards wherever there was plenty of water in the dry Summers.

The port includes the Cagliari International Container Terminal (CICT) at Giorgino, which had an annual traffic capacity of 1,000,000 Twenty-Foot equivalent units (TEUs) in 2002.

[16] Multinational corporations like Coca-Cola, Heineken, Unilever, Bridgestone and Eni Group have factories in this area.

There are religious buildings in the metropolitan area that date back to the beginnings of the Christian presence in Sardinia.

Little now remains of the Byzantine period: the only building that survives, is the small church of San Giovanni in Assemini.

A deep, sacred well is located in Settimo San Pietro and a giants' grave, Is Concias, in the territory of Quartucciu.

Within this forest is the WWF (World Wildlife Fund) Monte Arcosu Oasis, created to protect the subspecies of Sardinian deer (Cervus elaphus ssp.

The mountain of Sette Fratelli, which is covered by the forest, is a vast massif with many crested peaks, seven of which are visible from Cagliari.

One of the biggest is the Poetto beach of Cagliari and Quartu Sant'Elena, 10 km (6.2 mi) of fine sand in front of the Sella del Diavolo.

Its carriage, accompanied by Sardinian militiamen, the Alter Nos (the mayor's representative), folk groups wearing traditional clothes, on foot or on elaborately decorated waggons (traccas), and finally believers, proceeds for 32 km.

After the ceremony, the groom puts his pinkie in the ring of a chain that surrounds the waist of the bride, an ancient token of bond.

The Metropolitan City's indigenous language is Sardinian in its Campidanese variety, but it is losing ground to Italian almost everywhere.
