If you want to impress your fellow travelers, find the nondescript door to the Priory of the Knights of Maltaup on the Aventine Hill, just past the orange grove. Peep through the keyhole and you’ll spy a perfect view of Saint Peter’s Basilica across the city. No one knows if it was designed that way or if it was just a lucky coincidence, but the centuries-old building is truly majestic. Before entering the hands of the Knights of Malta, it was a fortified palace belonging to Alberico II, who ruled Rome from 932-954, a Benedictine monastery, and home
to the Knights of Templar.
