Mon-Sat: 9.30am-5.30pm; L4000. The park of the Palazzo Corsini is now the site of the Orto Botanico , which, after Padua’s botanical gardens, is the most important in Italy - and a good example of eighteenth-century garden design. Its highlights are a wood of century-old oaks, cedars and conifers, a grove of acclimatized palm-trees, in front of the so-called Fountain of the Tritons, an herbal garden with medicinal plants, a collection of orchids that bloom in springtime and primeval summer - and, a nice touch, a garden of aromatic herbs place together for the blind people; the plants can be identified by their smell or touch, and are accompanied by signs in braille. The garden also has the distinction of being home to one of the oldest plane trees in Rome, between 350 and 400 years old.
