Colonnella, a hilltop above the Val Vibrata near the sea

From the top of Colonnella's hill, at around 300 metres, the view reaches the Adriatic and the Tronto valley. The town lies in the northern part of the province of Teramo, close to the border with the Marche region: the coast and San Benedetto del Tronto are only a few kilometres away, and the A14 motorway runs along the shore.

The municipality has two sides. On the hill is the old centre, with tightly packed houses and steep streets; further down, towards the plain, newer residential and commercial areas have grown, and the data list 7 supermarkets, quite a few for a place of this size. People who work on the coast or in the business parks of the Val Vibrata can live here with short drives. Choosing between a house in the old village and one lower down makes a real difference: old walls and stairs on one side, recent buildings with parking and a garden on the other.

In 2023 there were 3,669 residents, down 2.6% on 2011 according to Istat, the national statistics office. The average age is 47.1, close to the provincial 46.7, over-65s make up 25.2% and foreign residents 9.5%. Declared incomes are slightly below the provincial average.

The province of Teramo is split between two seismic zones in the Civil Protection classification (the national emergency agency): 10 municipalities in zone 1 and 37 in zone 2. Colonnella is in zone 2, with an expected ground acceleration of about 0.178 g in the built-up area. For a house in the old centre, ask what work has been done on walls and floors; for a newer building, ask for the design year and the structural sign-off. The hillsides are steep, so the report checks the official landslide maps for the address and, lower down, the flood maps too.
