12270 Bozar           Discovered 1990 Aug. 16 by E. W. Elst at the European Southern Observatory.
The name "Bozar" for the Palais des Beaux-Arts in Brussels was inspired by the language of Brussels residents. Some 28~000 square meters are at the disposal of artists and the general public, fulfilling architect Horta's 1928 dream.
