Abstract
We study finite foldable cubical complexes of nonpositive curvature (in the sense of A D Alexandrov). We show that such a complex admits a graph of spaces decomposition. It is also shown that when , contains a closed rank one geodesic in the –skeleton unless the universal cover of is isometric to the product of two CAT(0) cubical complexes.
