Casarão da Alameda Cleveland, Historic mansion in Campos Elísios, São Paulo, Brazil

Casarão da Alameda Cleveland is a mansion designed by architect Ramos de Azevedo, built between 1890 and 1894 on a corner lot of Alameda Triumpho. It has high ceilings, wooden floors and decorative wall paintings, with predominantly European eclectic features. A neighboring residence, added in 1926 as a dormitory, follows the same architectural pattern.

The building was constructed between 1890 and 1894 and belonged to Henrique Santos Dumont, brother of aviation pioneer Alberto Santos Dumont. Its construction took place during São Paulo's economic expansion driven by the coffee trade.

The mansion takes its name from Cleveland Avenue and once housed a wealthy family during São Paulo's coffee boom era. Today visitors can see how the rooms were arranged and understand how affluent families lived in the city during that prosperous period.

The mansion stands at the corner of Alameda Cleveland in Campos Elísios, near the old Alameda Triumpho. The museum occupies ground-floor rooms and an upper floor, while the restored basement has a low ceiling and columns that make movement awkward. The neighbouring house, built as a dormitory for the Colégio Stafford, forms part of the same set.

The building retains painted walls and decorative details from the 1890s that are rare examples of artistic craftsmanship from that era. These original ornaments display the taste and skill that wealthy families valued in their homes.
