La Mortella (Italian: place of myrtles) is a private garden in the island of Ischia, Italy.
She opened the garden to the public in 1991 and handed over management and eventually ownership to the Fondazione William Walton.
[1][2] A museum dedicated to the life and work of William Walton is now part of the garden complex.
It hosts the William Walton Foundation and a Greek Theatre where Italian and foreign schools of music perform more than 70 weekend concerts, plus masterclasses and a programme for composers from Harvard University.
In 2004 it was awarded First Prize as il più bel parco d’Italia (the most beautiful park in Italy) by the American company Briggs & Stratton, against competition from 100 other gardens.
