The optical illusion of via Piccolomini - Roma | Secret World Trip Planner

From here you can enjoy an incomparable view of the dome of St. Peter's from a vantage point even better than the one you have from the square in front of the basilica. But what is even more amazing is the effect: approaching the dome it seems to shrink, while the further you go the more it enlarges until it overlooks the hills around. Via Piccolomini is geographically located near the hill of Gianicolo, in a raised position compared to the rest of the city. Moreover, it is perfectly straight, flat, about 300 meters long, and ending with an extraordinary belvedere over Rome. Absolutely to be seen both day and night.
