The garden is built within the remnants of a large Roman quarry known as the 'Cava romana'.
It contains preserved Punic-Roman cisterns, providing evidence of ancient water management techniques.
The garden hosts several 'living fossils', including specimens of Cycads that date back to prehistoric eras.
A portion of the garden is specifically designed to replicate the macchia mediterranea ecosystem found throughout Sardinia.
The botanical collection includes a notable variety of succulent plants, many of which are housed in a specialized greenhouse area.
The Orto Botanico di Cagliari is a historic botanical garden managed by the University of Cagliari, spanning approximately five hectares. It houses over 2,000 plant species, focusing heavily on Mediterranean flora alongside significant collections of succulents and tropical plants. The site is uniquely integrated into an ancient Roman quarry, with vertical rock walls framing the horticultural zones. It features a system of Roman cisterns and hydraulic structures that once served the ancient city of Karalis. The layout includes greenhouses, an arboretum, and a section dedicated to aquatic plants. Educational research remains a primary function of the facility, which serves as a living laboratory for the university. The garden is divided into distinct zones based on ecological and taxonomical criteria, including a palm grove and a citrus orchard.
The elevated paths overlooking the ancient Roman stone quarry walls and the integrated palm grove.
Wear sturdy, closed-toe walking shoes, as the paths can be uneven and rocky due to the quarry terrain.
Apply sun protection before entry, as parts of the garden are exposed with limited overhead coverage.
Bring a reusable water bottle, as fountains are available to refill in the shade-covered areas.
Do not visit during the peak of midday in mid-summer, as the sun reflects intensely off the limestone quarry walls.
Typically closed on Mondays.
Maintain silence to protect the research environment; do not touch or collect plant specimens.
