Given a group G acting on a CAT(0) polygonal complex, X, it is natural to ask whether the structure of X allows us to deduce properties of G, for example whether G has a codimension-1 subgroup (and so does not have Property (T)), the Haageruup property, or even if G is special. We discuss some recent work on local properties that X may possess which allow us to answer these questions.
