Firstly, we have fitted the density parameters of the triaxial outer bulge and the inner old thin disc with DENIS data at |l| <12° and |b| <4°, and show that the bulge is very oblate, with an angle from the sun-Galactic center direction of ≈10°.

Secondly, we have compared Besançon simulations with CAIN data at 15° < l < 45° |b| ≤ 2°, and show the existence of an in-plane extra density of stars at l≤27°, with a distance from the sun at ≈6 kpc. This extended over-density might correspond to the top end of a bar having a half-length of about 4 kpc and an angle of 45°±9°.
