Most of the extragalactic objects detected so far in the very high energy (VHE) regime are blazars, but detected nearby radio galaxies: M87, Cen A and NGC 1275 of type FRI seem to constitute a new class of VHE emitters. The radio galaxy PKS 0625-354 was observed with the H.E.S.S. phase I telescopes in 2012, above the energy threshold of 250 GeV. The time-averaged TeV energy spectrum is well characterized by a power law model. The broad-band spectral energy distribution (SED), including the available multiwavelength data, as well as the VHE data gathered with H.E.S.S. will be presented.
