Decode the Tapajós Star Chart — A Lost Civilization's Secret

Your quest begins at Praça Rodrigues dos Santos, a historic central square in Santarém built in the 19th century as the commercial and administrative heart of the city. Surrounded by neoclassical buildings dating from the 1850s-1870s, including the Câmara Municipal inaugurated in 1883, this 10,000 m² area has been a place for public gatherings since Santarém's founding in 1661. It is here that the explorer Francisco Orellana, the first to navigate the Amazon in 1542, might have observed the beginnings of urban life. Augmented reality clues guide you to symbols engraved on the facades, revealing the first coordinates of the "Mapa Celeste" and immersing you in Santarém's National Historical Heritage.

Your journey then takes you to the Encontro das Águas, the confluence point of the Tapajós and Amazonas rivers, visible 5 km from Santarém. This natural phenomenon, where the clear waters of the Tapajós meet the muddy waters of the Amazonas over a 10 km stretch, has been studied by science since Orellana's expedition in 1542. For the indigenous Tapajós culture, this site was sacred. You are now on the Rota dos Encontro das Águas. Your phone reveals ancestral motifs superimposed on the landscape, helping you understand how this pre-Columbian civilization interpreted the stars and river currents for navigation and prosperity. It was here that Beta Hellmuth, in 1950, began to understand the richness of the Tapajós culture.

Continue your exploration to the Catedral Metropolitana de Santarém, consecrated in 1767 as Igreja Matriz and elevated to cathedral status in 1952. Its Portuguese Baroque architecture, with a 40 m long nave and a 35 m high bell tower, has witnessed the Círio de Nazaré procession since 1793. The cathedral was restored in 2010 after structural damage. Adjacent to the edifice, Praça da Matriz, developed in the 18th century, houses the statue of São Sebastião erected in 1900, patron saint of Santarém since 1661. The cathedral's ornaments and the square's engravings provide you with new symbols for the celestial map, allowing you to decipher the constellations used by the Tapajós to mark seasons and river floods.

The Mercado Municipal de Santarém, built in 1912 in Art Nouveau style by Belgian architect Gustave Cornudet, is your next stop. With a covered area of 4,500 m² and a capacity for 500 stalls, it has been a commercial center since the rubber era (1880-1910). It hosts the fish market, reflecting the importance of the Tapajós river for the local economy. A little further, the Centro Cultural João Fona, inaugurated in 2006 in the renovated historic building that was formerly Teatro Carlos Gomes from 1920, is dedicated to Tapajoara arts and culture, with exhibitions on indigenous history. It is named after João Fona (1890-1975), a local musician and founder of Santarém's first brass band in 1910. Among the market stalls and the center's collections, you discover hidden motifs that reveal the rituals and beliefs related to Tapajós stars and navigation.

Your journey concludes at Praça do Pescador, developed in the 1970s near the Tapajós river port. This 5,000 m² square, with its monuments to artisanal fishermen, reflects the local economy since the colonial era and is close to the Mercado do Pescador, operational since 1980. Observing the boats on the river, you assemble the final fragments of the "Mapa Celeste." The Tapajós culture, whose archaeological remains were identified in 1950 by Beta Hellmuth, has revealed its navigation and cosmology secrets to you. This interactive visit in Cidade Tapajônica will have allowed you to reconstruct ancient knowledge, understand the ingenuity of a lost civilization, and see Santarém as a crossroads between past and present, at the heart of Brazil's National Historical Heritage.
