Jenne, in the upper Aniene valley in the Simbruini mountains

Jenne lies in the upper Aniene valley, above eight hundred metres, in the Simbruini mountains, the most inland part of the metropolitan city of Rome. The land is almost all woodland and mountain and falls within the Monti Simbruini regional park. Subiaco is the nearest town for services, schools and shops; Rome feels far in travel time, even though it is not many kilometres away.

People buying here are usually after a family house to restore or a home for holidays and weekends. Houses are stone, built into the hillside, with steps and narrow lanes, so the roof, damp, wiring and plumbing and access need checking carefully. On the slopes and along the Aniene, the report checks the official landslide and flood maps at the address.

The population is elderly. In 2023 there were 320 residents, down 19.6% from the 398 of 2011, according to Istat, the national statistics office. The estimated average age is 56.3, against 46.0 in the metropolitan city, and over-65s make up 42.5%, against 22.9%. Foreign residents account for 0.6%.

Jenne is in seismic zone 2 on the Civil Protection Department's national scale, like 97 of the 121 municipalities in the metropolitan city, with expected ground acceleration of about 0.161 g, a medium value. In the Apennines, stone houses whose floors and roofs were redone without care are the most vulnerable, so ask what structural work has been done and have a surveyor assess it.

The Revenue Agency (Agenzia delle Entrate) cadastre is available for Jenne, and the report traces the land parcel from the address.
