Largo Marguerite Yourcenar, 1, 00010 Tivoli RM, Italy
The 2nd-century Roman emperor Hadrian spent much of his 20-year reign traveling through his empire, absorbing architectural inspiration from Greece to Egypt. His vision for a luxury villa was realized in Tivoli, a Roman suburb, where he constructed a sprawling palatial complex decked out with the finest statuary of the age. Hadrian’s Villa is a UNESCO World Heritage site, and it contains the ruins of over 30 epic structures. Be sure to check out the Maritime Theater, which Italian authorities managed to partially restore.
Piazza Trento, 5, 00019 Tivoli RM, Italy
When Cardinal Ippolito d’Este narrowly lost the Papal election, he assuaged his frustrations by embellishing a spectacular villa in Tivoli, a village in the hills east of Rome. The villa itself was brilliantly outfitted in 16th century frescoes, while the gardens were the highest achievement of hydraulic engineering for the age.
