Very-high-energy (VHE, E>100 GeV) gamma-rays provide a unique view of thenon-thermal universe, tracing the most violent and energetic phenomena at workinside our Galaxy and beyond. The latest results of the H.E.S.S. Galactic PlaneSurvey (HGPS) undertaken by the High Energy Stereoscopic System (H.E.S.S.), anarray of four imaging atmospheric Cherenkov telescopes located in Namibia, aredescribed here. The HGPS aims at the detection of cosmic accelerators withenvironments suitable for the production of photons at the highest energies andhas led to the discovery of an unexpectedly large and diverse population ofover 60 sources of TeV gamma rays within its current range of l = 250 to 65degrees in longitude and |b|<3.5 degrees in latitude. The data set of the HGPScomprises 2800 hours of high-quality data, taken in the years 2004 to 2013. Thesensitivity for the detection of point-like sources, assuming a power-lawspectrum with a spectral index of 2.3 at a statistical significance of 5 sigma,is now at the level of 2% Crab or better in the core HGPS region. The latestmaps of the inner Galaxy at TeV energies are shown alongside an introduction tothe first H.E.S.S. Galactic Plane Survey catalog. Finally, in addition to anoverview of the H.E.S.S. Galactic source population a few remarkable, recentlydiscovered sources will be highlighted.
