The historic ‘Keyhole’ of the Sovereign Order of Malta in Rome is widely known as one of the most impressive and unforgettable views of St. Peter’s Basilica. Not only is it framed elegantly by a thick laurel hedge adding to the enticing view, but through the small portal one can enjoy a unique view of three different states in a single glance: Vatican City, Italy, and the extraterritorial gardens of the Magistral Villa. It was the work of Giovanni Battista Piranesi that formed the ‘telescope’ effect around the dome of the basilica which has captivated visitors for centuries and continues to be a popular tourist attraction. This stunning view, combined with its impressive historical legacy, make the Keyhole of the Order of Malta definitely worth seeing!
