Posada, the Castello della Fava and the river mouth

The old village of Posada climbs a rocky spur above the plain of the river of the same name, topped by the remains of the Castello della Fava. This is the Baronia, on the north-east coast of Sardinia in the province of Nuoro: below the village the plain runs down to the sea, with long beaches and wetlands near the river mouth.

Buyers find two very different markets. In the old centre there are stone houses packed against the hill, with narrow lanes and flights of steps, not ideal if you want to park at your door. On the plain and towards the coast there are detached houses, holiday complexes and second homes, many occupied mainly in summer. The town hall stands at around 20 metres and the climate is mild, climate zone B. On the plain and near the river, the first thing to check is the flood maps, which the report looks up for the exact address.

Posada is one of the municipalities that are growing: according to Istat, the national statistics office, it had 3,024 residents in 2023, up 10.5% since 2011, and ranks 9 of 53 in the province by population. The average age is 47.1, against 48.3 for the province; over-65s are 24.5% and foreign nationals 5.4%. Declared incomes are a little below the provincial average.

Earthquake risk is low, zone 4 in the Civil Protection classification like almost all of Sardinia, with an expected ground acceleration of 0.050 g. In seaside homes, salt air, damp and the state of the systems matter more.

Key points

Overview

Posada is a municipality in the province of Nuoro, in Sardegna. At the end of 2023 it had 3,024 residents, ranked 9 of 53 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Posada is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 53 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 grown by 10.5%. The estimated average age is 47 years, in line with the province. 25% of residents are over 65 (the regional figure is 27%). Foreign residents make up 5.4% of the population. On average, a household has 1.9 members.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Posada: the report checks the address against the ISPRA maps.

House prices

The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.

Land registry

The cadastral maps for Posada are public: from the address the report finds the sheet and parcel number.

Liveability area by area
