Triggiano, on Bari's south-eastern edge

Triggiano borders Bari on the south-east, and for its residents the city is part of daily life: jobs, the university, hospitals and shops are only a few kilometres away. The town lies on flat land at about 60 metres, surrounded by olive groves and fields that in recent decades have given way to new housing.

Its layout is typical of the towns around Bari. There is a compact old centre with low stone houses and narrow streets, then a ring of apartment blocks built during the post-war expansion and the years that followed, where most flats on the market are found. In a block from that period, check the state of facades, balconies and shared services, and the maintenance work already planned.

Istat, the national statistics office, counted 25,866 residents at the end of 2023, down 4.2% since 2011. The average age of 46.0 is in line with 45.8 for the province, and foreign nationals are few, 2.3%. Average incomes are slightly below the provincial average. Cafés and restaurants are thinner on the ground than elsewhere in the province (3.87 per 1,000 residents against 5.00), a sign that many people head into Bari for an evening out.

As for earthquakes, Triggiano is in zone 3 of the national classification, like 33 other municipalities in the province, with a low expected ground acceleration of about 0.068 g. For the older houses in the centre it is worth looking at the condition of the walls and any work done on roofs and floors.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report identifies the land parcel from the address. Even on almost flat land, heavy storms can leave standing water, so the report reads the official flood maps for the exact spot.

Earthquakes

For Italy's Civil Protection Department, Triggiano is in seismic zone 3, a zone where strong earthquakes are possible but rare. Most municipalities in the province (34 of 41) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.068 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
