If one of the main objectives of Mexican mural painting was to communicate its message to the people, via monumental works, there is no better example than that offered by this cultural centre. This twelve sided construction also contains a restaurant, piano bar, theatre and bookshop, and is covered inside and out by 8,000 square metres of mural images. Siqueiros has created here, a combined painting and sculpture entitled The March of Humanity, which invites the viewer on a journey from the beginnings of the human race up to the present. On the outside, there is a mixed-media relief mural that uses twelve panels to fuse ideas about humanity and nature.
