6714 Montréal           Discovered 1990 July 29 by H. E. Holt at Palomar.
Host city for the IAU General Assembly in 1979, Montreal has combined the best of English and French cultures since its founding in 1642. The city has a rich astronomical tradition, as can be seen in several outdoor works of art that emphasize the city's connection to the stars.
