Trinità d'Agultu e Vignola, Isola Rossa and the Gallura coast
Trinità d'Agultu e Vignola covers a stretch of Sardinia's north coast, on the western side of Gallura. The village itself sits inland on a hill, while on the sea there are Isola Rossa, a small settlement with a harbour, and part of Costa Paradiso, with houses set among red granite rocks. These places are very different, and buyers need to know from the start which one they want.
Holiday homes dominate the coast, full in summer and quiet the rest of the year. There are 44 bars and restaurants listed, a lot for a municipality of this size, and almost all serve tourists. The inland village has the life of a small Gallura town, with basic services and a car for everything else. The port and airport of Olbia are reached by car across Gallura.
The population has grown. Istat, the national statistics office, counts 2,351 residents in 2023, up 9.1% since 2011. Foreign residents make up 13.4%, a high share for Sardinia, and over-65s 27.6%. Households are small, 1.95 people on average.
Sardinia has the lowest earthquake hazard in Italy. All 26 municipalities in the province are in seismic zone 4, the lowest class set by the Civil Protection department, with an expected ground acceleration of about 0.050 g. For a house by the sea, salt air, wind, the state of windows and doors and whether recent buildings have the right permits matter more.
The Revenue Agency's cadastral maps cover the municipality, and the report starts from the address to find the land parcel.
