Baronesa de Arary Building, Residential building on Avenida Paulista, São Paulo, Brazil.

The Baronesa de Arary is a large residential building on Avenida Paulista organized into four separate blocks, each with its own character. The structure rises across 25 floors and was designed as a cohesive complex with multiple dwelling configurations.

The building stands where Baroness Maria Dalmácia de Lacerda Guimarães had a mansion built on Avenida Paulista in 1917, designed by the French architect Victor Dubugras. Her title came from her husband, the São Paulo farmer José Lacerda Guimarães, whom she married and who had been granted the barony of Arary by D. Pedro II. The residence was later replaced by the current tower, which was shut down for lack of safety in 1993.

The building's nickname, "Treme-Treme da Paulista", comes from the slight sway residents feel on upper floors. Chef Henrique Fogaça used the name publicly and was fined R$ 500 for allegedly defaming the condominium. Pianist Pedrinho Mattar and actor Sérgio Cardoso also lived here.

The building stands on Avenida Paulista and is reached on foot from the surrounding blocks; the entrance serves residents and their visitors, so the lobby and lifts are not open to tourists. The four blocks are named Côte d'Azur, Rajá, Capri and Acapulco, and the 590 apartments hold roughly 3,500 people, so the common areas stay busy at most hours.

Residents call it "Treme-Treme da Paulista," a nickname still in use. Chef Henrique Fogaça used it and was fined R$ 500 for allegedly defaming the condominium. The building was shut down for lack of security in 1993.
