Tupulicus

Tupuliçus was an Indigenous settlement on the lower Tapajós, near the site later known as Alter do Chão. The broad river meets the waters of the Amazon farther north, while sandy shores and forest border its lower course. In 1626 the Portuguese expedition of Pedro Teixeira encountered people here; the settlement later became associated with a mission and the colonial village of Alter do Chão.

The later city of Santarém lies here.
