Boxiness associated with the morphology of the central parts of bars, is a feature usually encountered in the edge-on profiles of galaxies, or galactic models. However, there are cases where “boxy” isophotes are observed also in the central parts of nearly face-on bars. I summarize here some dynamical mechanisms that support boxy orbits in the central bar regions on the equatorial plane of the disks, or orbits with boxy projections on it. Such orbits could describe the dynamics of face – on boxy “bulges”.
