Prince Leone Massimo, last Minister of the Vatican Post, was a man of great culture particularly in the fields of art and music, to which his early twentieth century compositions within the circle Sauguet and the French musicians testify.
The Cultural Association commemorates him and was set up by his nieces Caterina di Carpegna, Lavinia Massimo, Ottavia Massimo and Elena Ricci and its activity is dedicated to the restoration of the Castle of Arsoli and renewed life therein.
