Phoenix Park, an important historic designed landscape, is reputedly Europe's largest enclosed urban park. It was laid out in the mid-late seventeenth century as a royal deer park, being commissioned by the viceroy James Butler, Duke of Ormonde. It was opened to the public, 1747, by Lord Chesterfield, making it Ireland's oldest public park. The many important groups of buildings, such as Áras an Uachtaráin and Dublin Zoo, each enclosed by their own boundaries and good planting, make it an ensemble of very considerable interest and importance. This is complemented by the presence of some significant isolated structures and monuments, such as the eighteenth-century Magazine Fort, nineteenth-century Wellington Testimonial, and twentieth-century Papal Cross. The varied landscapes within the park, ranging from open parkland to woodland and gardens, are of considerable value for recreation, and for fauna and flora. The extensive stone wall and the accompanying fine metal gates that enclose the park are an intrinsic part of its fabric.
