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.
