H.E.S.S. (High Energy Stereoscopic System) is a hybrid array of five imaging
atmospheric Cherenkov telescopes in Namibia, operating in the very-high-energy (VHE) gamma-ray energy range between ~20 GeV and 100 TeV. In the past decade H.E.S.S. has conducted deep observations of Galactic regions of utmost importance for understanding acceleration mechanisms of cosmic rays and production of VHE gamma rays. Among them are the Galactic Center and Ridge, the Crab Nebula, the energetic Vela pulsar, several supernova remnants (SNR) and pulsar wind nebulae (PWN). The H.E.S.S. Galactic plane survey (HGPS), conducted from 2004 to 2013, was the first high-resolution (~0.1 deg) and sensitive (~1.5% Crab Nebula point-source sensitivity) survey of the Milky Way in TeV gamma-rays. Comprising ~2800-hrs of observation time it revealed the existence of a diverse population of cosmic accelerators in the Galaxy.

This contribution will present the latest results from the Survey, including maps,
a comprehensive source catalog, a model for Galactic diffuse VHE emission and
association of H.E.S.S. sources with known pulsars and PWNe, SNRs, binary systems and
GeV sources detected by the Fermi-LAT. The presentation will highlight results of
systematic SNR and PWN source population studies as well as a selection of brand
new VHE sources, including newly identified shell-like SNRs.
