  Observations of the supernova remnant G22.7-0.2 in the field of view of W41
with the H.E.S.S. telescope array have resulted in evidence for a very high
energy (VHE) gamma-ray emission from the direction of the object. The emission
region is spatially coincident with molecular clouds visible in 13CO data,
suggesting a hadronic origin of the TeV emission, although other scenarios
brought by X-ray observations with the XMM-Newton satellite are also discussed.
The latest results obtained on this SNR with H.E.S.S. and associated
multi-wavelength information are presented here.
