We present the results of an in-situ study of the Galactic Halo through a
pencil-beam spectroscopic survey of the Chandra Deep Field South. State
of the art model atmospheres and spectrum synthesis techniques have been
used to determine chemical abundances, physical, kinematical and orbital
properties of each star of the sample. We found that the Galactic Halo
extends up to at least 165kpc from the Galactic Centre. Our stars
constitute a pure Halo sample with a mean [Fe/H]=-1.4 and a large metallicity
dispersion, covering the range -2.4[Fe/H}]-0.1. There is a suggestion
of a weak metallicity gradient in the Halo.
