The English Garden was added to the Reggia complex between 1785 and 1796 at the request of Queen Maria Carolina of Austria, who brought in English designer John Andrew Graefer to design it. It sits to the side of the formal park axis and offers a complete change of mood — winding paths, streams, a small lake, and carefully arranged "natural" scenery that is in fact entirely constructed.
The plantings include specimens brought from across the globe, including rare camellias and subtropical species that flourish in the mild Campanian climate. Dotted throughout are artificial ruins, grottos, and a small Cryptoporticus — a covered walkway half-buried in the hillside. It requires a separate ticket from the main park admission but is well worth the addition.
