Troina, a Norman town above a thousand metres

Troina stands more than a thousand metres up and is one of the highest towns in Sicily. It sits on a ridge on the edge of the Nebrodi mountains, in the north-east of the province of Enna, and was one of the Normans' first strongholds on the island. At the top of the town are the cathedral and the oldest quarters, with narrow, steep streets.

Troina is home to the Oasi Maria Santissima, a hospital and research institute specialising in intellectual disabilities, which employs many local people and explains why healthcare facilities per resident are far above the provincial average. The cities are far away and the roads are mountain roads, so most of daily life is organised locally. The housing market is small: in the old town there is no shortage of stone houses to restore, and outside it there are newer blocks and detached houses.

The population is falling fast. In 2023 there were 8,405 residents, 1,223 fewer than the 9,628 of 2011, a drop of 12.7% according to Istat, the national statistics office. The estimated average age is 47.6 against 46.4 in the province, and over-65s make up 27.6%. Foreign residents are few, at 1.8%. There are 12 schools and education sites, more per resident than the provincial average.

Troina is in seismic zone 2 of the Civil Protection classification, like 18 of the 20 municipalities in the province, with expected acceleration of about 0.141 g. In the old stone houses of the centre, often built against one another, ask whether walls and floors have been strengthened and check the roof, which has to carry snow and wind here.

At this altitude winters are long and cold, with snow almost every year, so insulation and heating weigh on running costs. The clay slopes around the town are prone to landslides: the report checks them at the exact address and, with the Revenue Agency (Agenzia delle Entrate) cadastral maps, traces the plot.

For anyone buying in Troina, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.
