Cherenkov telescope array to test a possible association of the gamma-ray emission with the SNR. With a total of 59 hours of observation, representing about four times the initial exposure available in the discovery paper of HESS J1731-347, the gamma-ray morphology is investigated and compared with the radio morphology. An estimate of the distance is derived by comparing the interstellar absorption derived from X-rays and the one obtained from 12CO and HI observations. The deeper gamma-ray observation of the source has revealed a large shell-type structure with similar position and extension (r~0.25{\deg}) as the radio SNR, thus confirming their association. By accounting for the H.E.S.S. angular resolution and projection effects within a simple shell model, the radial profile is compatible with a thin, spatially unresolved, rim. Together with RX J1713.7-3946, RX J0852.0-4622 and SN 1006, HESS J1731-347 is now the fourth SNR with a significant shell morphology at TeV energies. The derived lower limit on the distance of the SNR of 3.2 kpc is used together with radio and X-ray data to discuss the possible origin of the gamma-ray emission, either via inverse Compton scattering of electrons or the decay of neutral pions resulting from proton-proton interaction. %G English %Z HESS %L in2p3-00596124 %U https://hal.in2p3.fr/in2p3-00596124 %~ IN2P3 %~ OBSPM %~ CEA %~ INSU %~ UNIV-PARIS7 %~ X %~ UNIV-SAVOIE %~ UPMC %~ UGA %~ LAPP %~ LLR %~ LPNHE %~ APC %~ CNRS %~ UNIV-GRENOBLE1 %~ UNIV-MONTP2 %~ INPG %~ IRSTEA %~ CNES %~ OSUG %~ LUTH %~ X-LLR %~ X-DEP %~ X-DEP-PHYS %~ LUPM %~ IPAG %~ DSM-IRFU %~ IRFU-APC %~ PSL %~ AGREENIUM %~ UPMC_POLE_2 %~ MIPS %~ UNIV-MONTPELLIER %~ CEA-DRF %~ SORBONNE-UNIVERSITE %~ LUPM_EMA %~ SU-SCIENCES %~ INRAE %~ UNIV-PARIS %~ UP-SCIENCES %~ OBSPM-PSL %~ USMB-COMUE %~ SU-TI %~ ALLIANCE-SU %~ UM1-UM2 %~ LPNHE-2
