Ploaghe, a hill town in the Logudoro

In the Logudoro area south-east of Sassari, Ploaghe sits on a rise surrounded by pasture, arable fields and olive groves. It is the birthplace of Canon Giovanni Spano, the 19th-century archaeologist and scholar of the Sardinian language, and it keeps an old centre of stone houses on sloping streets.

Buyers choose between houses in the old centre, often old and in need of work, and newer homes on the edge of town. Sassari is the reference point for work, hospital and university, and is about half an hour away by car. In the historic centre, check the condition of roofs and floors and any damp in the stone walls.

The population is shrinking: 4,242 residents in 2023, down 8.8% on 2011, or 411 fewer people. The average age is 47.7, close to the province (48.3), and over-65s make up 27.6%. Foreign residents are few, at 1.4%. Average declared incomes are in line with the province.

Seismic risk is minimal: all 66 municipalities in the province of Sassari are in zone 4, the lowest in the national classification drawn up by the Civil Protection Department, and the expected ground acceleration is about 0.050 g. In climate zone D the winters are mild but damp, and an uninsulated stone house can feel cold.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps for Ploaghe too: the report traces the address to its plot and checks the official landslide and flood maps for that exact point, including along the streams in the countryside.

Key points

  • Hill town in the Logudoro, south-east of Sassari.
  • 4,242 residents, down 8.8% since 2011.

Overview

Ploaghe is a municipality in the province of Sassari, in Sardegna. At the end of 2023 it had 4,242 residents, ranked 11 of 66 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Ploaghe is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 66 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.

Population

Compared with the 2011 census, the resident population has fallen by 8.8%. The estimated average age is 48 years, in line with the province. 28% of residents are over 65 (the regional figure is 27%). Foreign residents make up 1.4% of the population. On average, a household has 2.2 members.

Ploaghe is in climate zone D, with 1,701 heating degree days: heating may be switched on from 1 November to 15 April, for up to 12 hours a day. The same table puts the town hall at 425 metres above sea level.
