Aiello del Friuli, the sundial village on the Friuli plain
Aiello del Friuli is known as the village of sundials: dozens of them decorate the fronts of houses and courtyards, painted and restored over the years. It lies on the lower Friuli plain, between Palmanova and Cervignano, among farmed fields, ditches and rows of trees, less than 20 metres above sea level. Udine is the provincial capital of reference, while the beaches of Grado and Lignano are a short drive away.
Homes are mostly detached houses and courtyard houses, with some rural buildings to restore. On this plain, read the official flood maps for the address, because ditches and channels are everywhere. Declared incomes are slightly below the average for the province of Udine.
One practical point: Aiello is among the municipalities that use the tavolare land register, the land book system inherited from Austrian rule. Ownership and mortgages are recorded in the land book (libro fondiario), and that is where the notary checks the title. The Revenue Agency (Agenzia delle Entrate) maps are still published, and the report uses them to find the land parcel.
Istat, Italy's national statistics office, counted 2,121 residents in 2023, down 6.6% on 2011. The mean age is 50.7, against 48.5 in the province; over-65s make up 31.3% and foreign residents 4.6%.
Aiello is in seismic zone 3, with an expected ground acceleration of 0.142 g; in the province of Udine 19 municipalities are in zone 1 and 71 in zone 2. In courtyard houses, look at the roofs and the ties between walls and floors.
