The upper garden was designed and developed by Lady Walton beginning in 1983, the year Sir William Walton passed away. Where the lower garden is enveloping, intimate, humid, and luxurious, the upper garden is sunny, open (with many wonderful views of the surrounding area), and generally cultivated with Mediterranean vegetation. The upper garden is punctuated by surprising architectural elements, many of which are imbued with symbolic significance and make references to the history and archeology of the island of Ischia. There are two ways to reach the upper garden. The first is to climb one of the many sets of steps that wend their way up the hillside. The second is by driving through the woods to the parking area near the olive grove at the upper entrance to the garden.
