הגן הבוטני של קליארי (Orto botanico di cagliari) - יוני 2015 One of Italy’s most famous botanical gardens, the Orto Botanico was established in 1858. Today it extends over five hectares and nurtures 3000 species of flora. Leafy arches lead to trickling fountains and gardens bristling with palm trees, cacti and ficus trees with huge snaking roots. Specimens from as far afield as Asia, Australia, Africa and the Americas sidle up to the local carob trees and oaks. Littering the gardens are a Punic cistern, a Roman quarry and an aqueduct
