Castel di Lama, between the old hilltop and the Tronto valley
Castel di Lama has two sides. The old village sits on a hill at around two hundred metres, while most homes have gradually moved down into the Tronto valley, in the districts that grew up around Piattoni along the valley roads. The municipality lies between Ascoli Piceno, about ten kilometres away, and the coast at San Benedetto del Tronto.
For anyone working in Ascoli or on the coast it is well placed, as the Ascoli to the sea expressway runs along the valley floor. Buyers choose between the newer detached houses and small blocks lower down, close to shops and services, and the houses of the hilltop village, quieter but often in need of updating. It is one of the more populous towns in the province.
The population is almost unchanged: 8,431 residents in 2023, 0.5% fewer than in 2011, according to Istat, the national statistics office. By the standards of the Marche it is young, with an estimated average age of 45.0 against 47.8 for the province and over-65s at 23.1% (province: 27.0%). Households average 2.51 people and foreign residents make up 8.1%.
Earthquakes matter here. Castel di Lama is in seismic zone 2 of the Civil Protection classification, like 32 of the 33 municipalities in the province, and expected acceleration in the built-up area is about 0.176 g, a medium-high value. Before buying, ask whether the building has been surveyed or seismically upgraded, including with public incentives, and get the paperwork.
On the valley floor the Tronto and its side streams can flood the lowest ground, and on the hill the slopes can slide. The report tells the two apart by reading the official maps at the exact address, and uses the Revenue Agency (Agenzia delle Entrate) cadastral maps to trace the plot.
