« Freedom, though late »— Official motto of the city of Ouro Preto
Your quest for the manifesto begins at Praça Tiradentes, the historic heart of Ouro Preto. This central square is named in homage to Joaquim José da Silva Xavier, known as Tiradentes, a key figure of the Inconfidência Mineira, executed in 1792. The monument dedicated to Tiradentes stands in the center, marking the starting point of Brazilian independence movements. Surrounded by 18th-century colonial buildings, the square reflects the baroque mining architecture that made Ouro Preto famous, a UNESCO World Heritage site. Here you collect the first clues, hidden in the details of the facades.
Continue to the Museu da Inconfidência, housed in the former Palácio dos Governadores, built in the 18th century. This museum preserves documents, letters, and objects related to the 1789 Inconfidência Mineira, a revolutionary movement against the Portuguese Crown. You examine personal artifacts of Tiradentes and his co-conspirators, which document the political manifesto of the revolt. It is here, among the evidence of the conspiracy, that fragments of the hidden text might be revealed, inserted into the narratives of the struggle for Brazilian freedom.
Your journey then takes you to the Igreja Matriz de Nossa Senhora do Pilar, built between 1728 and 1751, one of Ouro Preto's oldest churches. Its richly adorned interior of gold and baroque sculptures testifies to the region's gold prosperity in the 18th century. A place of worship frequented by the colonial elite, it also saw members of the Inconfidência Mineira pass through. The Chafariz do Alto da Cruz, an 18th-century colonial public fountain, offers a panoramic view of the city and its baroque churches, a strategic point to observe the movements of authorities and revolutionaries.
The Casa dos Contos, an 18th-century colonial building, was formerly the seat of the Portuguese tax administration (Casa de Fundição). It was here that the gold tax (derrama) was collected, the main economic grievance that motivated the Inconfidência Mineira. Now a museum, it documents the monetary and administrative history of the colonial period. The Igreja de São Francisco de Assis, built between 1765 and 1810, is a masterpiece of late Brazilian baroque, with its facade sculpted by Aleijadinho, a major artist whose work expresses a sense of cultural independence.
Finally, your investigation leads you to the Museu do Oratório, housing a collection of 18th-century oratories (portable altars). These private cult objects, used by the mining elite and families linked to the Inconfidência, reflect colonial baroque piety and devotional practices of the era. Along the way, the Mirante Morro da Queimada offers a perspective on the entire city of Ouro Preto, Minas Gerais, and its Brazilian historical monuments. You have now gathered the pieces of the puzzle, allowing you to reconstruct Tiradentes' Hidden Manifesto, a victory for the cultural heritage of Brazilian Sudeste.
