Galaxy formation and evolution is still one of the fundamental open questions in modern astrophysics. Nearly 25% of visible light emitted in the local universe originates from bulges embedded in galactic disks, therefore a crucial step to address the problem of galaxies formation and evolution is the characterisation of these structure. In this context, the Milky Way bulge offers a unique opportunity being the only laboratory in which we can study in detail the stellar populations as well as the chemical composition and kinematics on a star-by-star basis. I will give an overview of the Bulge stellar populations properties as derived from the latest photometric and spectroscopic surveys, and present recent results on the age and mass of the Bulge.
