Brignano Gera d'Adda, the Visconti palace near Treviglio
The centre of Brignano Gera d'Adda is dominated by Palazzo Visconti, a large aristocratic residence dating from the time when the Gera d'Adda was a border land between the Duchy of Milan and the Republic of Venice. Today the town lies in the lowlands of the province of Bergamo, just north-east of Treviglio and north of Caravaggio, on a plain of fields watered by irrigation channels.
The municipality has no railway stop of its own, but Treviglio station is a few kilometres away, with frequent trains to Milan and Bergamo, and the Brebemi motorway runs a little further south. That is why Brignano appeals to people who work in the Milan area and want a bigger home than they would find next to the station. Most buildings are villas and small blocks of flats from recent decades, with a few farmhouses and courtyard houses in the old core.
There were 6,154 residents in 2023, 3.7% more than at the 2011 census. The population is younger than the provincial average: an average age of 43.4 against 45.2, with over-65s at 19.4%. Foreign nationals make up 11.8%, and average incomes are almost exactly those of the province.
An old courtyard house to restore has its charm but needs care: walls of brick and river stones, timber floors, rising damp. The whole province of Bergamo is in seismic zone 3 of the national classification drawn up by the Protezione Civile (Civil Protection Department), and here the expected ground acceleration is about 0.114 g. Before renovating, have an engineer assess the structure and ask about the tax incentives for seismic strengthening.
Irrigation channels cross the land in many places, so flood hazard is checked address by address on the official maps, which is what the report does. The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps here, and the report can trace the plot.
