It became famous and a much sought-after tourist destination, thanks to Porto Pino, a 'pearl' of the Mediterranean of dazzling beauty and harmonious ecosystem with placid lagoons, lush greenery, fine white sand dunes and a clear, turquoise sea. Sant'Anna Arresi is a pretty village with almost three thousand inhabitants in Lower Sulcis, with thousands of natural, cultural attractions including food and wine. An independent municipality since 1965, it stretches across a hill that dominates a plain rich with coastal ponds (Porto Pino, Maestrale, Corvo, is Brebeis and Foxi), that are the home to black-winged stilts and flamingos. The lagoon area is delimited by the promontory of Porto Pino, covered by a vast pine forest with extremely rare Aleppo pines, kermes oaks and junipers, as well as Mediterranean scrub. Along the Arresi coast, between little coves of pink sand, long 'desert-like' beaches and reefs with breathtaking seabeds, the Caribbean paradise of Porto Pino stands out. It is a four-kilometre long expanse of sand divided into the 'first' beach and 'second' beach, that borders with is Arenas Biancas, the impressive and pure white dunes in the territory of Teulada. In the locality of Porto Pinetto, you will find another 'gem': cala dei Francesi, a half-moon of white sand with fragments of coral, washed by a sea with reflections of emerald green and blue.

The name of the village combines the patron saint with the nuraghe Arresi, around which the original nucleus of rural houses emerged in the 18th century and little by little led to the establishment of the present-day village. The nuraghe 'a tancato', that is with two towers (the main one is seven metres tall and 13 metres in diameter) united by walls that enclose a courtyard, dates back to the Middle Bronze Age (15th-14th century BC). It stands in the main square, halfway between the 'old' church of Sant'Anna and the new parish church dedicated to the saint, who is celebrated at the end of July with a procession in traditional dress. Every year, in early September, a famous event, which is part of the musical summer, has been taking place in the square of the Nuraghe since 1986: A combination of Sardinia and jazz, it is brought to life by great artists from the world of international jazz. It is preceded by the feast of fish in August.

The Nuragic age in Sant'Anna is also documented by a source (that can be visited) inside the village and by various other nuraghi and Tombs of Giants in the countryside, among which the Coi Casu, inhabited between the Early and Late Bronze Age (17th-11th century BC), consisting of a complex nuraghe with a large village around it, the remains of which you will be able to admire. The territory became very important later on: the cove of Porto Pino was a maritime seaport in the Phoenician-Punic age and a mercantile centre under Roman domination.
