The majestic Rio Branco Palace is more than just the official residence of the Acre state government; it is the primary architectural symbol that the city of Rio Branco takes pride in. Built in Neoclassical style, this building stands out from the urban landscape with its massive Doric and Ionic columns, reminiscent of the grandeur of ancient temples. Constructed of brick in an era when wood predominated in the region, the palace was a true breakthrough in local architecture and engineering.

Today, this historic monument in Brazil serves an important educational role: its first floor is entirely dedicated to a museum exhibition. Here, through photographs, artifacts, and interactive materials, the dramatic and rich history of the Acre people is revealed—from ancient geoglyphs to the present day. The second floor still retains its status as a venue for official state ceremonies.
Surrounded by well-kept gardens, fountains, and squares, Rio Branco Palace forms a harmonious cultural ensemble. This site attracts visitors with its atmosphere of continuity between generations and its status as a state-protected cultural heritage site.
