Forte do Presépio (formally Forte do Castelo do Senhor Santo Cristo do Presépio de Belém) is a fort located in Belém, Pará, Brazil. It was built in 1616 by Francisco Caldeira Castelo Branco at Maúri Point, a promontory on the right bank of the mouth of the Guamá River and Guajará Bay. The first chapel in Belém was located in the fort. It was a temporary structure and was dedicated to Our Lady of Grace, and was moved a few years later to the current Largo da Sé, and became the Cathedral of Our Lady of Grace in the 18th century. The fort was listed as a historic structure by the National Historic and Artistic Heritage Institute in 1961.
