I will review our current knowledge about the structure and stellar population of the Galactic bulge and of its Nuclear region, spatially overlapping with the Central Molecular Zone. I will also present new photometric and spectroscopic programs that will target the bulge innermost region in the next few years, promising to transform our

The WST project aims to design and construct an innovative 10-metre class wide-field spectroscopic survey telescope (WST) in the southern hemisphere. It will feature the parallel operation of two cutting-edge instruments: a high-multiplex (30,000), large field-of-view (3 square degrees) multi-object spectrograph (MOS) operating in both low- and
