We report preliminary results of the observation of the GRB 021004 host galaxy and field obtained with the new VLT/X-shooter spectrograph. Thanks to the X-shooter wide spectral range we could detect many emission lines associated to the GRB host at z=2.33102. Moreover we identify [O III] λλ 4959, 5007 Å emission lines at z=2.33184 associated with a close-by galaxy possibly interacting with the GRB host. We do not detect any counterpart of the foreground absorbers found in the afterglow spectra of GRB 021004.
