  We present a deep near-infrared wide-angle photometric analysis of the
structure of the inner Galactic bar and central disk. The presence of a
triaxial structure at the centre of the Galaxy is confirmed, consistent with a
bar inclined at 22+/-5.5 deg from the Sun-Galactic centre line, extending to
about 2.5 kpc from the Galactic centre and with a rather small axis ratio. A
feature at l=-9.8 deg not aligned with this triaxiality suggests the existence
of a second structure in the inner Galaxy, a double triaxiality or an inner
ring. We argue that this is likely to be the signature of the end of the
Galactic bar, at about 2.5-3 kpc, which is circumscribed by an inner
pseudo-ring. No thick dust lane preceding the bar is detected, and a hole in
the disc's dust distribution inside the bar radius is inferred.
