The keyhole view at the Sovereign Order of Malta is a hidden gem in Rome, offering a unique and captivating perspective of St. Peter's Basilica. Visitors line up day and night to peek through the keyhole at the entrance of the Magistral Villa, where the illusion of the basilica's dome appearing larger and closer creates a magical sight. This picturesque spot, framed by laurel hedges and designed by Giovanni Battista Piranesi in the 18th century, provides a stunning view that captures the essence of Rome's beauty and history.
