Both, observational and theoretical results support the close connection between bars and box/peanut-shaped bulges in spiral galaxies. However, for the sub-class of thick box/peanut-shaped bulges, an environmental process instead of an internal mechanism is suggested to account for the prominence of the box/peanut component. In this paper a multi-wavelength study of the morphology and the kinematics of a sample of thick box/peanut-shaped bulges is presented. The results suggest a scenario in which interaction events play a significant role in the history of thick box/peanut-shaped bulge galaxies. Most likely these sources have experienced a mass infall.
