Gaggi, the Alcantara valley near Taormina

Gaggi lies in the lower Alcantara valley, at the southern tip of the province of Messina, a short distance from the coast at Giardini Naxos and from Taormina. On clear days Etna is visible behind. The village has grown along the road that runs up the valley, surrounded by citrus groves and vegetable plots.

For buyers, being close to the tourist coast and to the services of Taormina and Giardini is the main advantage. Homes are village houses and recent blocks of flats, often built in stages. In the low-lying areas near the river and the streams coming down from the hills, the report checks the address against the official flood and landslide maps.

There are 3,088 residents (2023), down 1.6% since 2011. The average age is 44.2, below the provincial 46.7; over-65s are 21.3% and foreign residents 5.0%. Declared incomes are below the provincial average.

Earthquake risk needs to be taken seriously: Gaggi is in zone 2, like 90 other municipalities in the province, with expected ground acceleration in the built-up area of 0.210 g. In buildings put up in stages, sometimes with extra floors added later, check the planning permits and the structural certification.

The climate zone is B, with mild winters. The Revenue Agency publishes cadastral maps and the report goes from the address to the plot.

For anyone buying in Gaggi, 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.
