The weird thing about this street is that is the further away from St Peter’s you get, the bigger it seems to become.
This amazing view is from a residential street on the hill to the south-West of the Vatican, near Villa Doria Pamphili.

It’s about 15 minutes’ walk from Baldo delgi Ubaldi Metro station (Linea A) or the same from San Pietro train station, up a steep hill overlooking the dome of St Peter’s Basilica.
The street – a well-heeled residential avenue – is named for Niccolò Piccolomini, who was made archbishop of Benevento in 1464 by Pope Pius II, but died a mere three years later.
