Castelmassa, on the banks of the Po in the upper Polesine
Castelmassa lies on the left embankment of the Po in the upper Polesine, in the western part of the province of Rovigo. On the far bank is Lombardy and the town of Sermide, and a bridge over the river links the two. The centre huddles against the embankment, with flat farmland all around, only a few metres above sea level.
It is a small service centre for nearby villages, with shops, schools and small businesses. The market includes two- or three-storey village houses, small villas on the edges and flats in blocks from the 1960s and 1970s. Average declared incomes are above the average for the province of Rovigo; for work people also look to Ostiglia, Legnago and the Mantua area.
The population is falling. In 2023 there were 3,985 residents, 7.1% fewer than the 4,291 recorded in 2011 by Istat, the national statistics office, and the average age is 48.4. Over-65s make up 29.1%, just above the provincial 28.1%, and foreign residents 13.0%.
All 50 municipalities in the Polesine are in seismic zone 3 of the Civil Protection classification, and in Castelmassa the expected ground acceleration is about 0.091 g. Soft alluvial soils can amplify shaking: for brick houses, ask about the condition of load-bearing walls and floors, and check for rising damp, common near the river.
The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps and the report finds the plot from the address. Water is the main issue here: the Po flows just beyond the embankment and the land is crossed by drainage channels, so flood hazard should be read from the official maps for each individual address.

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