With its grassy banks and colorful flower beds, this leafy park is a wonderful place to escape the crowds and enjoy a summer picnic. At its center is a 16th-century villa housing the Italian Geographical Society, while to the south stands a 12m-plus Egyptian obelisk. In July, it's the setting for a much-loved summer jazz festival.
Legend surrounds this ancient monument, with one story holding that the globe on top contains the ashes of the emperor Augustus. Another tells how a workman lost his arm while erecting the obelisk and that the severed limb is buried beneath its base.
