Villasimius, Capo Carbonara and the sea of south-east Sardinia

At the south-eastern tip of Sardinia, Villasimius occupies the Capo Carbonara headland, with white beaches, granite coves and a marine protected area that also takes in the islands of Cavoli and Serpentara. Behind the coast lies the Notteri lagoon, visited by flamingos, and behind the town are hills of Mediterranean scrub. Cagliari is reached by car along the scenic coast road or through the interior, a journey that gets longer with summer traffic.

Beach tourism has transformed the town within a few decades. The market is largely second homes, villas, holiday complexes and flats, in a town that fills up in summer and shrinks again in winter. If you are buying to live here all year, check which services stay open out of season; if you are buying to let, find out about local and regional rules on short-term rentals. Near the coast, landscape protection is strict and planning compliance must be checked carefully. Average declared incomes are slightly above the provincial level.

In 2023 there were 3,721 residents, up 8.8% on 2011 according to Istat, the national statistics office. The average age is 48.3 against 48.1 in the province, and over-65s make up 23.8%. Foreign residents account for 4.9%.

Seismic risk is minimal: all 70 municipalities in the province are in zone 4, the lowest class of the Civil Protection classification, with an expected acceleration of about 0.050 g. Climate zone C brings mild winters; wind and salt air add to the upkeep of façades and window frames.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps. Low-lying areas near the lagoon and the streams can flood in heavy rain, so the flood map is checked for the address.

Overview

Villasimius is a municipality in the province of Cagliari, in Sardegna. At the end of 2023 it had 3,721 residents, ranked 26 of 70 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Villasimius is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 70 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.050 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.
