The Boboli Gardens is a park in Florence that is home to a collection of sculptures dating from the 16th through the 18th centuries, with some Roman antiquities. Behind Palazzo Pitti, the Boboli Gardens were laid out in the mid-16th century to a design by architect Niccolò Pericoli. At the upper southern limit you have beautiful views over the Florentine countryside and at the lower end of the gardens, there is a fantastical shell and gem encrusted grotto.
Piazza Pitti, 1, 50125 Firenze
These gardens offer wonderful shady spaces in the summer, but remember these are gardens, and not a playpark, so its formality might make it less appealing to children. (KH)
