  Among all the high-energy environments of our Galaxy, the Galactic Center
(GC) region is definitely the richest. It harbors a large amount of non-thermal
emitters, including the closest supermassive black hole, dense molecular
clouds, regions with strong star forming activity, multiple supernova remnants
and pulsar wind nebulae, arc-like radio structures, as well as the base of what
may be large-scale Galactic outflows, possibly related to the Fermi Bubbles. It
also contains a strong diffuse TeV gamma-ray emission along the Galactic ridge,
with a disputed origin, including the presence of a possible Pevatron,
unresolved sources, and an increased relevance of the diffuse sea of cosmic
rays. This very rich region will be one of the key targets for the next
generation ground-based observatory for gamma-ray astronomy, the Cherenkov
Telescope Array (CTA). Here we review the CTA science case for the study of the
GC region, and present the planned survey strategy. These observations are
simulated and we assess CTA's potential to better characterize the origin and
nature of a selection of gamma-ray sources in the region.
