Located on the left of the Via Flaminia, which goes from Rome towards the Adriatic Sea, Acquasparta, as its Roman name – ad aquas partas or “among the waters” - implies, is situated at the centre of an area rich in springs surrounded by Roman ruins and rugged wooded hills.
Belonging to the so-called Terre Arnolfe, an independent fiefdom of the Papal States, Acquasparta preserves the urban structure of the period of its greatest development, when, during the Renaissance, it was ceded by the Farnese to the princely Cesi family, who in the 2nd half of the XVI century had Giovanni Domenico Bianchi build a grand residence, Palazzo Cesi, on the ruins of the old fortress.
The rooms of the palazzo, where in 1609 Federico Cesi reconstituted the Accademia dei Lincei which he had founded six years earlier, were decorated in two distinct phases:  around 1579 the artist Giovan Battista Lombardelli worked there and then, starting in 1618, Federico il Linceo took over and worked there with a northern European painter based in Rome and a Late Mannerist Roman painter.  Galileo Galilei was a guest there during those years.
The main street of the town is Corso Umberto I and on it rises the renaissance-era church of S. Cecilia and the Oratorio del Sacramento, home to a Roman-era mosaic taken from the nearby Carsulae (San Gemini), which was an old Roman municipality that had been destroyed by the Longobards and by earthquakes and where, still today, fascinating ruins can be seen.
The area is known for its thermal baths and the Furapane spring water, which contains medium levels of minerals and calcium carbonate, and the springs of Amerino water, containing mildly radioactive calcium carbonate, which was so dear to the poet Gabriele D’Annunzio.
