Italy
Two millennia of water engineering, from Hadrian's pools to Renaissance fountains powered by gravity.
Water is everywhere here: channelled through stone, forced skyward by nothing but gravity, pooled in the ruins of an emperor's private world. The sound shifts as you move, from the thunder of the Oval Fountain to the hiss of the Hundred Fountains to the still mirror of Hadrian's canal.
Tivoli holds two UNESCO World Heritage sites a short ride apart. Villa Adriana, Emperor Hadrian's second-century retreat, quotes the empire back to itself with an Egyptian canal, Greek theatres and Roman baths. Villa d'Este, finished for Cardinal Ippolito d'Este in the 1570s, drives hundreds of jets and a self-playing water organ from the Aniene, diverted into the hillside above its terraces. Fourteen centuries separate the two obsessions with water; thirty kilometres separate both from Rome, and most visitors to the capital never come.
Solo
Villa Adriana is vast enough to lose a day in; the scale of one man's ambition lands hardest walked alone.
Couple
Walk the Hundred Fountains in drifting mist, then let the afternoon dissolve at a garden trattoria.
Family
Fountains that play music and five hundred jets firing at once beat any screen, and Hadrian's ruins are a natural playground.
Tivoli's pizzutello, an elongated sweet grape, appears on stalls when the September harvest lands.
