Castel Madama, the Orsini castle above the Aniene valley

Castel Madama is gathered around the Orsini castle at the top of a hill above the Aniene valley, just beyond Tivoli and about forty kilometres from Rome. The name recalls Margaret of Austria, daughter of Emperor Charles V, known as Madama, who held the fief in the sixteenth century. Olive groves and hills surround the town, and the valley carries on towards Subiaco and the mountains on the Abruzzo border.

If you work in Rome, the links are there: the A24 motorway from Rome to L'Aquila has a junction named after the town, and the railway to Tivoli and Avezzano has a station down in the valley. The old centre sits high up, with narrow, steep streets and houses built against each other; newer buildings and detached homes are lower down, along the roads leading into the valley.

There are 7,026 residents (2023), down 4.1% since 2011. The average age of 46.0 matches that of the Rome metropolitan area; over-65s are 23.4% and foreign residents 9.0%. Declared incomes are well below the provincial average, although that average includes the capital.

Castel Madama is in seismic zone 2 of the Civil Protection classification, like most municipalities in the province (97 out of 121), with an expected ground acceleration of about 0.153 g. Stone houses in the old town, altered many times over the centuries, should be seen by a surveyor before you buy; the same goes for floors added over the years to more recent houses.

On the sides of the hill landslides are possible, and on the valley floor near the Aniene flooding: the report checks the hazard maps for the address and uses the cadastral maps from the Revenue Agency (Agenzia delle Entrate).

For anyone buying in Castel Madama, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.
