Santa Maria la Longa, on the Friuli plain between Udine and Palmanova
Santa Maria la Longa is a municipality on the Friuli plain south of Udine, along the route towards Palmanova and the lowlands. The landscape is flat and agricultural, with fields, rows of trees and small scattered villages. Udine is the reference point for work, schools and the hospital, and is a short drive away.
The municipality is made up of several villages, and much of the land is farmed. Buyers find traditional Friulian houses built around a courtyard, often renovated, as well as newer detached homes. A car is essential for almost everything. On land close to ditches and canals, the report checks the official flood maps for the address.
Istat, the national statistics institute, counts 2,298 residents in 2023, down 4.9% since 2011. The average age is 48.9, in line with the 48.5 of the province of Udine, foreign residents make up 5.9% and households have 2.40 members on average. Declared incomes are below the provincial average.
Friuli has a seismic history that still shapes how people build. Santa Maria la Longa is in seismic zone 3 on the Civil Protection Department scale, but the expected ground acceleration is 0.156 g, a value worth taking seriously; further north, towards the hills and mountains, municipalities are in higher classes. For an older house, ask for the year of construction and whether it has been rebuilt or strengthened.
The climate is zone E, with cold, damp winters. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report reaches the plot from the address.
