DESCRIPTION:In the last years\, our knowledge of galaxy formation in the e
 arly Universe has grown considerablyDeep multi-wavelength HST observations
  of the main extragalactic fields (such as CANDELS and the Frontier Fields
 ) have allowed us to identify galaxies up to redshift 10\, derive the evol
 ution of the UV luminosity function and SFR density up to these early epoc
 hs. Progress is not limited anymore by statistics\, but by the systematic 
 uncertainties in some of the crucial physical properties of galaxies such 
 as dust\, metallicity\, ionizing emissivity and so on. Systematic spectros
 copic follow up is  needed as a key complement both to validate the above 
 results but most importantly to probe the ISM conditions\, gas kinematics\
 , chemical enrichment and to understand the environmental impact on galaxy
  evolution.\nIn this talk I will present VANDELS:a VIMOS survey of the CAN
 DELS UDS and CDFS fields\, the latest ESO VLT public spectroscopic survey 
 which has obtained ultra deep optical  spectra with up to 80 hours of inte
 gration  of > 2100 galaxies at 1.5 < z < 6 . I will present some of the mo
 st important early results\, which highlight the impact of working with hi
 gh S/N spectra of  distant galaxies to assess their physical properties.\n
