Giudizio Universale opens its doors for the pope's special guests.

Pope Francis has invited 1,300 poor people, including homeless, refugees, needy families and even prisoners to a special screening of Giudizio Universale: Michelangelo and the Secrets of the Sistine Chapel.

The charity event has been organised by the office of the Apostolic Almoner and has been made possible after the show's organisers, Artainment Worldwide Shows, made available all 1,300 seats for free.

A permanent fixture at the Auditorium Conciliazione near St Peter's, the cutting-edge production immerses the audience in the world of Michelangelo's masterpiece in the Sistine Chapel through a mixture of live performances and spectacular special effects.

Created with scientific advice of the Vatican Museums and with original music by Sting, the 60-minute show features immersive 270-degree 3D projections designed to "leave the audience breathless".
