Previously owned by the Prado family, powerful local coffee barons, this beautifully preserved mansion houses a museum focused on interior design. The permanent collection includes furniture from the 17th to the 21st centuries, but the museum also hosts temporary exhibitions as well as an annual design award event. There’s a great restaurant here too – Quinta do Museu – and, on Sunday mornings, the terrace and garden are the site of delightful free music performances.
