We review observations of spiral or lenticular barred galaxies having inside their primary bar either a misaligned inner (secondary) bar or a misaligned triaxial bulge. Some CCD near-IR images are presented. Galaxies with a nuclear ring, as well as our Galaxy, are considered as other likely candidates for having bars within bars. Some cases cannot be explained in terms of projection effects on two perpendicular bars. No favoured angle between the two stellar bars is found. The secondary bar… CONTINUE READING
