Just around the corner from the Edifício Sé [1] is the pretty pink Solar da Marquesa dos Santos (Rua Roberto Simonsen 136, Centro, tel. 11/3105-2030, www.prodam.sp.gov.br/dph/museus/solar [2], 9 a.m.–5 p.m. Tues.–Sun., free). São Paulo [3]’s oldest residential dwelling, this 18th-century mansion’s former occupants included the Marquesa de Santos, who was the (most famous) mistress of Emperor Dom Pedro II.
Today, it houses a small museum with temporary art exhibits devoted to different aspects of the city.
