In 144 b.C. consul Quintus Marcius Rex completed a 90 km aqueduct bringing water from the Simbruini Mountains to Rome. 80 km run underground, other 10 km on the arches still crossing the city. It ended on the Capitolium hill, at this fountain you can still drink the "clarissima aquarum omnium" (clearest of all waters) described by Pliny the Elder, the Roman historian killed in Pompeii by the Vesuvius eruption.
