Barberini Garden, Castel Gandolfo, near Rome
The pope’s summer palace, Castel Gandolfo has only recently been opened to garden lovers. The gardens are on the south-west shore of Lake Albano and built over the ruins of an ancient Roman villa, Albanum Domitiani. It has a grand belvedere, and a perfectly pruned Italian parterre. This is one of the very few gardens you can visit and admire in the pouring rain (a rare event south of Rome), thanks to a Roman cryptoporticus, or covered passageway. There is a magnificent magnolia collection and a model farm that grows produce for the pope’s table.

Villa Reale di Marlia, Lucca, Tuscany
The Royal Garden of Marlia, whose first owner was Napoleon Bonaparte’s sister, Princess Elisa Baciocchi, has recently undergone a major restoration. A luxurious green lawn, the teatro di verzura, laid in the 17th century, rolls from the Renaissance villa down to a picturesque lake. This has been restored, with terracotta statues in their original places. Trees, shrubs, camellias and boxwood hedge walks have been cut back to the original size and shape designed by Jacques Gréber in 1924. The colourful Spanish garden is particularly impressive, with fountains fed by a network of irrigation channels.

Castello Visconti, Grazzano Visconti, Emilia Romagna

Roses and hydrangeas add colour and variety in summer, and there is a children’s play cottage. The nearby village of Grazzano Visconti was created in neo-medieval style by the duke’s grandfather.

San Giuliano, near Siracusa, Sicily
Halfway between Catania and Siracusa, the 60-hectare grounds of the Marquis of San Giuliano’s estate include four hectares of garden and groves producing a million kilos of oranges; their scent fills the air. In 1990, landscape designer Oliva di Collobiano created a garden of four distinct spaces enclosed by drystone walls. There’s an Arabian garden, with ponds and water lilies; a tropical garden, with palms and monumental cacti; a Mediterranean garden with roses and grapefruit trees; and a scented garden, with frothy helichrysum, liquorice plant, myrtle and citrus. Rachel Lamb, the British head gardener, has added a new area dedicated to varieties of cactus.
