The Optical Gravitational Lensing Experiment (OGLE, Udalski et al.~1994a;Paczy\'nski et al.~1994b -- these proceedings; and references therein) is anextensive photometric search for the rare cases of gravitational microlensingof Galactic bulge stars by foreground objects. It provides a huge data base(Szyma\'nski \& Udalski 1993), from which color-magnitude diagrams have beencompiled (Udalski et al.~1993, 1994b). Here we discuss the use a ofwell-defined population of bulge red clump stars to investigate the presence ofthe bar in our Galaxy. The results of our earlier studies are described byStanek et al.~(1994).
