The Sphere Within Sphere, also known as Sfera con Sfera, is a series of sculptures created by Italian sculptor Arnaldo Pomodoro depicting an enormous metal sphere with a cracked surface revealing an intricate interior with another cracked sphere inside. Pomodoro originally created it for the Vatican Church in the 1960s, but later began building them for other organizations and can now be found in prime locations all over the world such as the Headquarters of the UN in New York, Trinity College in Dublin, The Christian Theological Seminary in Indianapolis, USA, The Tehran Museum of Contemporary Art, the Columbus Museum of Art in Columbus and the Tel Aviv University in Israel, to name a few.
