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