Inner bars are frequent structures in the local Universe and thought to substantially influence nuclear regions of disc galaxies. In this study we explore structure dynamics inner by deriving maps radial profiles their mean stellar population content comparing them previous findings context main bars. To end, exploit observations obtained with integral-field spectrograph MUSE three double-barre...
