In the heart of the city of Guanambi, located in the state of Bahia, Brazil, lies a unique architectural monument — the Dona Dedé Memorial House (Memorial Casa de Dona Dedé). This majestic mansion in the Neoclassical style was built back in the 19th century and stands as a living witness to the region's history. The mansion impresses with its scale: its 510 square meters feature 32 windows and 26 doors, while its facade is adorned with elegant decorative elements typical of elite buildings of that era.

Today, the building serves not only as a museum but also as an important cultural center for the city. Inside, there is a rich library with over 3,000 books and a documentation center that houses valuable archival materials about the founding of Guanambi. The mansion's interiors recreate the daily atmosphere of the early 20th century, allowing guests to see authentic furniture and household items belonging to the Martins de Oliveira family, who once owned this home.
The layout adds a special charm to the place: a central door flanked by four windows and a cozy veranda with wooden lattices at the back of the house. This home is a symbol of generational continuity and a primary attraction for anyone looking to discover the cultural heritage of the Brazilian Northeast.
