The great central span holds a particularly privileged location in the Pavilhão Bienal, outlined as it is by the enormous ramp from the ground floor and the guard rails between the second and third levels and it stand a generous fifteen metres high. One of the enormous advantages of this span is that from it, some of the work may be seen from numerous points of view.

In the following images, one can see the manifold possibilities this space offers and just how differently it has been occupied in the biennials since 1981. At times it brought together various artists, on other occasions work on a far grander scale took over. It has even been a stage for performances…
