The Quirinale Palace complex encloses a garden of almost four hectares whose history is closely associated with the evolution of the monumental compound.
On entering the Palace from Via del Quirinale through the Porta Giardini and a 19th Century gate, one proceeds along the Viale delle Palme, a road lined on both sides by geometric flower beds hosting a wide variety of arboreal species.
The Boschetto (Thicket), once characterized by an original layout, is separated from the garden by tall walls and hedges. The walks were arboured and the remaining spaces were covered by a thick vegetation that gave the whole area the appearance of a wood.
