  Central Compact Objects (CCOs) are a handful of sources located close to the
geometrical center of young supernova remnants. They only show thermal-like,
soft X-ray emission and have no counterparts at any other wavelength. While the
first observed CCO turned out to be a very peculiar magnetar, discovery that
three members of the family are weakly magnetised Isolated Neutron Stars (INSs)
set the basis for an interpretation of the class. However, the phenomeology of
CCOs and their relationship with other classes of INSs, possibly ruled by
supernova fall-back accretion, are still far from being well understood.
