All travel guides to Brazil recommend visiting the Government Palace and Cathedral of Our Lady of Nazareth in Rio Branco. However, these types of attractions can be found in almost every city not only in Brazil but throughout South America. There is a completely different reason to visit this city: Rio Branco is the "capital of the latex state". On its territory, there is even the Museum of Rubber, where you can learn about the times of rubber superiority.

The original museum was opened in 1978 in Rio Branco with the support of the Governor of Acre - Geraldo Gurgel de Mesquita. The purpose of its creation was to collect, research, preserve, and disseminate knowledge about the socio-economic history and culture of the Brazilian state. Besides, various seminars and courses of the museum are part of the educational program of some educational institutions. The modern museum has spacious showrooms with valuable exhibits as well as the library, which stores about 4700 volumes of rare publications. The archives of the museum contain numerous photographs and documents, manuscripts, and journals of the old rubber plantations of Acre.

The permanent exhibition of the museum is a brief overview of the history of the state. It is dedicated to the times of the discovery of rubber, the revolution, and the decline of the rubber industry. The total collection includes more than 5,300 exhibits, divided into the museum's thematic halls: paleontology, archeology, ethnography, sacred and fine art.

The paleontology section is represented by fossils of prehistoric animals such as the jaws of mastodons and extinct crocodile species. The archeological collection consists of funeral urns and vases decorated with anthropomorphic figures and belonging to the indigenous people of Brazil - the peoples of Pirarrãs. Other sections include many household items and culture, as well as hunting tools of the Amazon tribes: arrows, bows, and maces.

In 2013, the museum was closed due to serious electrical problems found in the building. After a five-year hiatus and restoration, the Museum of Rubber was reopened in 2018. The restorers gave new life to the cultural spaces. They restored the original architecture of the building. Moreover, new elements of the dominance of rubber appeared on the territory of the museum.
