Box- and Peanut-Shaped Bulges

Based on N-body simulations and kinematical evidence the phenomenon of box- and peanut-shaped (b/p) bulges in galaxies is now usually explained by resonances or instabilities caused by bars. New results on a detailed statistical study addressing the frequency of such box/peanut bulges and a small NIR imaging survey will be presented. These new results are discussed with regard to the origin of b/p bulges. In particular it is shown that some large and boxy bulges might be caused by merging.
