Today the Austrian Gallery in the Belvedere, in its Augarten Contemporary branch, shows popular special exhibitions. Apart from the Gustinus Ambrosi Museum, the building complex, which was designed in 1956 by Georg Lippert (1908-1993), also includes a sculpture garden, an apartment for an "artist in residence," and a restaurant (open daily 10 am - midnight).

Ambrosi's expansive oeuvre includes more than 2000 sculptures in stone and bronze. Along with memorials, fountains, and tombstone statues, he dedicated himself primarily to portrait paintings. He sculpted the likenesses of politicians, popes, businessmen, doctors, and merchants as well as contemporary artists, poets, philosophers, and composers.
