  The detection of the high-frequency peaked BL Lac object (HBL) SHBL
J001355.9-185406 ($z$=0.095) at high (HE; 100 MeV$<$E$<$300 GeV) and very
high-energy (VHE; $E>100\,{\rm GeV}$) with the \fer\ Large Area Telescope (LAT)
and the High Energy Stereoscopic System (H.E.S.S.) is reported. Dedicated
observations have been performed with the H.E.S.S. telescopes, leading to a
detection at the $5.5\,\sigma$ significance level. The measured flux above 310
GeV is $(8.3 \pm 1.7_{\rm{stat}}\pm 1.7_{\rm{sys}})\times 10^{-13}$ photons
\cms\ (about 0.6% of that of the Crab Nebula), and the power law spectrum has a
photon index of \indexHESS. Using 3.5 years of publicly available \fla\ data, a
faint counterpart has been detected in the LAT data at the $5.5\,\sigma$
significance level, with an integrated flux above 300 MeV of $(9.3 \pm 3.4_{\rm
stat} \pm 0.8_{\rm sys})\times 10^{-10}$ photons \cms\ and a photon index of
$\Gamma = 1.96 \pm 0.20_{\rm stat} \pm 0.08_{\rm sys}$. X-ray observations with
\textit{Swift}-XRT allow the synchrotron peak energy in $\nu F_\nu$
representation to be located at $\sim 1.0\,{\rm keV}$. The broadband spectral
energy distribution is modelled with a one-zone synchrotron self-Compton (SSC)
model and the optical data by a black-body emission describing the thermal
emission of the host galaxy. The derived parameters are typical for HBLs
detected at VHE, with a particle dominated jet.
