Quarto d'Altino, the Sile, Roman Altinum and the lagoon
Quarto d'Altino is the last stretch of mainland before the northern Venetian lagoon, along the course of the river Sile. Within its boundaries lies Altino, the Roman town of Altinum where the history of this area begins: the national archaeological museum holds its finds, and the excavations sit in open country. The rest is low-lying land, much of it reclaimed, with fields, canals and a town that grew up around the railway.
For commuters the location is one of the best in the province. The station on the Venice to Trieste line reaches Mestre in a few minutes, the Quarto d'Altino exit on the A4 motorway is right by the town, and Venice Marco Polo airport is close, as is Treviso. The market consists of detached and terraced houses and small blocks of flats; along the Sile and towards the lagoon there are country houses and villas with land.
In 2023 Istat, the national statistics institute, counted 8,068 residents, 1.6% fewer than the 8,199 of 2011. Compared with the Venice metropolitan area the town is younger: an average age of 46.4 against 47.6, with over-65s at 23.9% against 26.0%. Foreign residents account for 10.0%.
All 44 municipalities in the metropolitan area are in seismic zone 3 of the Civil Protection classification, and in Quarto d'Altino the expected ground acceleration is about 0.094 g. The hazard is moderate, but on soft, low-lying ground foundations matter: for a house built without a recent design, ask about cracks, settlement and past repairs.
The town hall stands just a few metres above sea level, and this is what deserves the closest attention. The land depends on embankments and pumping stations, and near the Sile and the canals flood hazard should be read for the individual address, as the report does. The Revenue Agency (Agenzia delle Entrate) cadastral maps are published and the plot can be found from the address.

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