Abstract: The Optical Gravitational Lensing Experiment (OGLE) data on high-amplitude δ Scuti Stars (HADS) and RR Lyrae stars have been analyzed to determine the distance to the galactic bulge. We find a mean value of 14.47 +/- 0.08 mag for the bulge distance modulus. A small additive correction leads to 7.9 +/- 0.3 kpc as the best distance to the galactic center.
