Marajó Island — The Lost Codex Conspiracy

Your quest for the Marajoara codex begins at Praça da Matriz, Macapá's central square, built in the heart of the city's historic northern district. This site, home to the main cathedral, has been a gathering place since Macapá's foundation in 1758 by the Portuguese. The square, approximately 5,000 m² in area, is surrounded by 18th-century colonial buildings, and its name refers to the adjacent matriz church, built in 1761. It is here that the first instructions to decipher the codex symbols await you, hidden in the shadows of the colonial arcades.

Your first stop takes you to the Igreja Matriz de Nossa Senhora do Rosário, Macapá's main church, erected in 1761 under Portuguese administration. Its Portuguese Baroque architecture, with a 30-meter-long nave, testifies to the Amazonian colonial ambition. Restored in 2008 after damage from the equatorial tropical climate, it still houses relics related to 17th-century Jesuit missions in Brazil's Norte region. These artifacts are the keys to unlocking the first pages of the codex. From there, you walk along the Orla de Macapá, a riverside promenade developed in 2005 along the Amazon River, stretching 2 km. This protected area harbors mangroves dating back 5,000 years and Marajoara archaeological relics, immersing you in Amapá's distant past.

Continuing your journey, the Palácio do Setentrião, an episcopal palace built in 1837, stands before you. The historic seat of the Macapá bishopric in the northern district, this Portuguese neoclassical style building was the bishop's residence from 1840 to 1970, a figure involved in the evangelization of local Amerindian populations. Now a municipal museum since 1995, it exhibits pre-Columbian artifacts from Marajó Island, offering a glimpse into the cultures that preceded the arrival of the Portuguese. The Marco Zero do Equador, a monument inaugurated in 1993, then marks your exact crossing of the equator, 1.5 km from the center. Its 30-meter-high concrete structure, with a rotating observatory, commemorates Macapá's unique geographical position, a scientific reference point since 1880, and a landmark for ancient navigators.

Praça da Bandeira, created in 1900, was a colonial administrative center near Praça da Matriz. It houses the statue of Tamandaré, a Brazilian admiral (1831-1880), erected in 1922, standing 5 meters tall. This site of patriotic ceremonies since the Proclamation of the Brazilian Republic in 1889, is surrounded by republican buildings from the 1920s. It is on Rua Cândido Mendes, a few steps away, that you will find clues to reconstruct ancient explorer maps. Finally, Parque do Forte reveals the remains of the Fort of São José de Macapá, built in 1764 by the Portuguese. This 1.5-hectare fortification, with its 4-meter-high walls of rammed earth, was the site of the first defense against French invasions in 1783. Restored in 2010, it holds the final riddles of the codex.
