I will discuss the recent discovery of the three black holes (BH) by Gaia astrometry, concentrating on BH3 , with a mass of 33 M_solar, which is orbited by a very metal poor giant in an orbit of 12 years. The BH in the Gaia BH3 system is more massive than any other Galactic stellar-origin BH known. The Galactic orbit of the system and its metallicity indicate that it probably belongs to the ED-2 stream, which likely originated from a globular cluster that was disrupted by the Milky Way.
