After surveying the remains of Villa Adriana on a Monday morning in 2018, I took the bus to the centre of Tivoli. From there I walked to the entrance of Villa Gregoriana. This park, built in the 19th century on the orders of Pope Gregory XVI, solved the problems of the frequent overflowing of the river Aniene and the resulting floods. The Pope's order was prompted by a major flood in 1826. Fortunately, however, the architect commissioned for this task killed two birds with one stone, designing not only a civil engineering structure, but also an exceptional garden inspired by the Romantic movement.

The visit begins with a winding descent to the bottom of the valley, along its high cliffs. The first point of interest is the view of the Mount Catillo tunnel through which the Pope had the river channelled and diverted. The water meets the Great Waterfall and falls dramatically by 130m as soon as it leaves the tunnel. This is not the most beautiful waterfall in the park, but it is probably the most impressive. A viewing platform at the base provides a nice vantage point. Still, the trail is punctuated by many other waterfalls in a beautiful setting with lush vegetation. The Siren's and Neptune's Grottas are also notable, as is the Miollis Tunnel. A few minor ruins can be found throughout the park. Finally, as the first half of the trail descends into the valley, it is necessary to finish the hike by walking back towards the town. The last point of interest on the trail is the Roman temples of Vesta and Tiburnus. From here there is a beautiful view of more waterfalls and the Ponte Gregoriano.

All in all, I really enjoyed my visit to this park. The nature is lush and rich and it mixes with a very interesting culture. It took me a little over an hour to complete the whole tour. Yes, the visit is relatively short, but it is well worth it. I do not believe that the Villa has an outstanding universal value as an example of a romantic garden. I see it more as a remarkable integration of a civil engineering work into a dramatic and beautiful environment. So I give this TWHS a thumbs up. Next destination: walking to the Villa D'Este.
