  I review the present status of ground-based gamma-ray astronomy,
concentrating on the population of galactic TeV sources. A number of new
telescope systems are now being completed, and promise to yield exciting new
discoveries, expanding rapidly the number of sources. The TeV galactic sources
today include a number of plerions, shell-type SNR, an X-ray binary, and also
one unidentified candidate. Their present status, and our understanding of
their TeV gamma-ray emission processes are summarised and some motivation
driving development of the field is outlined.
