Incontri in Terra di Siena is a not-for-profit cultural association, based at Villa La Foce in Tuscany, Italy. It was founded in 1988 by cellist Antonio Lysy and his mother Benedetta Origo in memory of Antonio Origo and his wife Iris, the well-known Anglo-American writer. After moving to the area in 1924, the Origos dedicated their lives to the development and progress of the Val d’Orcia and its people.

From the outset, the aim of the festival was to spread the appreciation of music and art through concerts, meetings, exhibitions and cultural events to be held in the many beautiful neighbouring towns of the Val d’Orcia such as Pienza, Montefollonico, Città della Pieve, Sarteano and Castiglioncello del Trinoro.
