At the end of the 20th century, thanks to the construction of new districts, it underwent considerable expansion and its inhabitants doubled. Today, with almost 70 thousand residents, Quartu Sant'Elena is the third largest town on the Island, after Cagliari and Sassari. Once an agricultural centre, today its wine-growing production is still alive and it is renowned for its Malvasia wine. Its jewellery made using gold filigree is also famous, as is its production of breads and homemade pastries: candelaus, pabassinas and piricchitus. Its territory is located between: the Campidano plain, the mountains and the woods of the Oasis of Sette Fratelli and the Molentargius-Saline park, which you can visit on foot or by bike and admire greater flamingo colonies. The Quartu coast starts from the shoreline of Poetto and stretches for tens of kilometres along the eastern part of the Golfo degli Angeli. There is a mixture of sheer cliffs and sandy or pebbly beaches: Capitana, with a tourist port and, behind it, hills covered in poplars and eucalyptus trees, the natural pools of Is Mortorius, Cala Regina with pebbles and a blue sea, the beautiful Is Canaleddus and the spectacular Mari Pintau, where smooth stones are bathed by the 'painted sea' with its dazzling colours. Lastly, there is Geremeas, with its soft, white beaches: Kala 'e Moru and Marongiu.
