We derived oxygen abundances for 42 K giants in four fields towards the Galactic bulge. We present here the results for Oxygen, as measured from the forbidden line at 6300 Å. Oxygen shows a well defined trend with [Fe/H]. with [O/Fe] being higher in bulge stars than in thick disk ones, the latter already more oxygen enhanced than thin disk stars (Bensby, Feltzing, & Lundström 2004). This result supports the scenario that the bulge formed faster and probably earlier than the thick disk.
