Located in Piazza dei Cavalieri di Malta, 3
Situated on top of the Aventine Hill just some foot steps away from Il Giardino degli Aranci are the famous Headquarters of the Knights of Malta. This location is one of the most interesting and curious places in Rome, you will see a line of people waiting to peek into the keyhole of the door of the Knights of Malta.
If you look through the keyhole you will perfectly see the spectacular Saint Peter's Basilica. You will be speechless, it is just an amazing view and so unusual that you can see the Vatican so clearly. Enjoy!
