The current progress of spectroscopic studies of heliumlike systems will be reviewed. Special emphasis will be given to both the groundstate as well as to the excited state investigations. For the heaviest ions, the potential of precision spectroscopy will be outlined and its relevance for atomic structure investigations will be discussed.
