Full of towering pine trees, atmospheric palms and scattered villas, this splendid 19th-century park once belonged to Prince Giovanni Torlonia (1756–1829), a powerful banker and landowner. His large neoclassical villa, Casino Nobile , later became the Mussolini family home (1925–43) and, in the latter part of WWII, Allied headquarters (1944–47). These days it houses an art museum.
