As early as 10 Gyr ago, galaxies with more than 10 ^11 M_sun in stars already existed. While most of these massive galaxies must have subsequently transformed through on-going star formation and mergers with other galaxies, a small fraction (<0.1%) may have survived untouched till today. Searches for such relic galaxies, useful windows to explore the early Universe, have been inconclusive to date: galaxies with masses and sizes like those observed at high redshift (M_*>10 ^11 M_sun; R_e<1.5 kpc) have been found in the local Universe, but their stars are far too young for the galaxy to be a
