Housed in a beautifully restored mansion, the Museu da Borracha has three small rooms with exhibits on the history of rubber-tapping. One room explains the extraction and processing of rubber, including the transition from using small axes (which killed the tree) to a tool called a cabrita (little goat), which only scrapes the surface. Other displays cover migration into Acre, the life and work of Chico Mendes and the Rural Workers Union, and relations with indigenous communities.
