Gran Priorato di Roma dell'Ordine di Malta

"The garden of the Gran Priorato di Roma dell'Ordine di Malta is a beautiful and tranquil space located on the Aventine Hill in Rome, Italy. The garden is open to the public for tours and is a popular spot for visitors to enjoy the views of the city. The garden is divided into two sections: the upper garden and the lower garden. The upper garden is the more formal of the two, with manicured lawns, hedges, and flowers. The lower garden is more informal, with trees, shrubs, and a small fountain. A highlight of the garden is the Buco della Serratura, or "Keyhole View." This is a small hole in the door of the Villa del Priorato di Malta that frames a view of the dome of St. Peter's Basilica. The view is said to be one of the best in Rome. "
