Abstract
As a bright and complex region seen at multiple wavelengths, the Galactic Centre has been a prime candidate for observations with the H.E.S.S. imaging atmospheric telescope array since data taking started in 2003. During over a decade of observation H.E.S.S. has revealed that in addition to a strong, point-like source coincident with the supermassive black hole Sgr A* the Galactic Centre region also contains a number of other sources. We will report on the latest results obtained by the H.E.S.S. experiment on the Galactic Centre region. These results include the spectral characterisation of the central source down to below 100 GeV, a detailed study of the diffuse ridge of gamma-ray emission extending up to 200 pc from it, the detection of a new TeV source, HESS J1746-285, in the inner 50 pc region, and the recent discovery of the existence of a powerful cosmic PeVatron at the center of our Galaxy.
