  We present the first-ever images of the circumstellar environment of the
carbon-rich AGB star II Lup in the infrared and sub-mm wavelengths, and the
discovery of the envelope's non-spherical morphology with the use of
high-angular resolution imaging techniques with the sparse aperture masking
mode on NACO/VLT (that enables diffraction limited resolution from a single
telescope) and with ALMA. We have successfully recovered images in $Ks$
(2.18$\mu$m), $L'$ (3.80$\mu$m) and $M'$ (4.78$\mu$m), that revealed the
non-spherical morphology of the circumstellar envelope around II Lup. The
stellar surface of the AGB star is unresolved (i.e. $\leq30$ mas in $Ks$)
however the detected structure extends up to 110 mas from the star in all
filters. Clumps have been found in the $Ks$ maps, while at lower emission
levels a hook-like structure appears to extend counter-clockwise from the
south. At larger spatial scales, the circumstellar envelope extends up to
approximately 23 arcsec, while its shape suggests a spiral at four different
molecules, namely CO, SiO, CS and HC$_3$N, with an average arm spacing of 1.7
arcsec which would imply an orbital period of 128 years for a distance of
590pc.
