Description
In this contribution, several aspects of the discovery of the Milky Way
hosting a central bar are briefly reviewed, as well as some minimal
introduction about the barred galaxies in the local Universe. The bulk
of the contribution is however dedicated to the two main lines of
thought about the true nature of the Galactic bar: that which argues for
the Galactic bulge being elongated, i.e. a triaxial body, in the plane
of the Galaxy, thus providing a bar-like structure in central regions.
The angle of that structure with respect to the Sun-Galactic centre line
is found to be about 23 deg. And the second one which claims for the
existence of a long thin bar, very much concentrated in the Galactic
plane, and being a distinct structure of the central Bulge. The position
angle in the latter case is calculated at about 45 deg.
