Hidden gems and unique experiences in Rome
Before you head for an eye-test, let us explain some of the reasons behind the strange things you see.
1. Through the keyhole
The keyhole of this enigmatic green door holds a secret - a direct view of the Dome of St Peter. Join the queue of other curious travellers to get a glimpse of the basilica. Technically the grounds beyond are not actually in Italy - as it’s owned by the Priory of the Knights of Malta which is a separate sovereign entity.
2. Now you see it, now you don’t
When you visit St Peter’s Square (Piazza San Pietro) keep your eyes peeled for a small circular marker made from marble. It says “centro del colonnato” on it. Now stand on it and face the columns. There are actually 284 columns in total which are four deep. But as if by magic they disappear and you can only see one row of columns. Step off the marker and the other rows reappear. This will keep you amused for several minutes. It’s known as Bernini's illusion (after the architect and sculptor who designed much of the square) and the Grand Illusion.
3. So close yet far away
One of the oddest optical illusions in Rome can be seen as you head up Via Niccolo Piccolomini. You can see the vast dome of St Peter’s as you approach the top of the road. However, as you get closer to the peak of the hill - the further it appears to be away and smaller it seems.
