As the nearest environment for studying some of the most exotic phenomena in the Universe, the Galactic Centre is one of the most well-studied regions in astrophysics, and routinely the subject of ground-breaking discoveries and surprises. Recent and upcoming observations from ground, airborne and space-based telescopes, such as VLT, HST, JWST, SOFIA, ALMA, VLA and MeerKAT, as well as advances in theory and numerical simulations, have led to significant progress in our understanding of this complex region. Nevertheless, our picture is far from complete. There are many open questions that are currently highly debated in the field, including the inward transport of matter and the feeding of the central black hole, the physical processes that determine the star formation efficiency in the Central Molecular Zone, the formation of the Nuclear Bulge, the 3D geometry of this region, and the origin of the Galactic outflow associated with the Fermi Bubbles/x-ray chimneys and the associated non-thermal filaments.
