Crumbling as they may be, B.A.'s early-20th-century buildings remain some of the finest examples of South American architecture. One gem is the Pasaje Barolo (1370 Avda. de Mayo), Mario Palanti's 1923 structure with a rotating lighthouse cupola and a façade inspired by Dante's Divine Comedy. On San Martín square, the Kavanagh Building (1065 Florida) was the city's first skyscraper, a late-1930s sliver of masonry by Sánchez, Lagos, and De la Torre. Across town in Palermo Chico, the Home of the National Fund for the Arts (2831 Rufino de Elizalde) occupies the late writer Victoria Ocampo's former residence, built in 1928. The architect was Alejandro Bustillo, who combined his classical training with budding modernist ideas.
