One of Rome’s seven incredible hills, Aventine Hill (Aventino) is situated farthest to the south along the Tiber River and is home to the fifth-century Basilica of Santa Sabina, Rose Garden, Orange Garden, and, perhaps most famously, Knights of Malta "keyhole" perspective. Numerous tours of royal and old Rome comprise Aventine Hill. In antiquated times it was the site of the Temple of Diana. Today the churches and gardens of the calm residential district offer a quiet respite.
