Pevas, located at the mouth of the Ampiyacu River in Peru, holds significant historical and cultural importance. Established in 1735 by Padre Adan Viedman, a Jesuit priest, Pevas stands as the oldest settlement in the Peruvian Amazon. Originally situated in the village of the Shishita River, it was later relocated to its current position on the Ampiyacu by Padre Valdivia in 1851. This move marked a significant transition for Pevas, as it became renowned for its "medicinal waters," as suggested by the Quechua translation of Ampiyacu. The area around Pevas, at the time of its founding, was inhabited by various indigenous peoples, including the Pebas, Caumaris, Boras, Huitotos, and Ocainas. Today, Pevas is the capital of the Distrito de Peva and home to approximately 3,500 residents, with a total population of around 12,000 spread across 80 villages within a 24,000 square mile area. As the commercial center of the region, Pevas plays a crucial role in the export of fruits and fish to nearby cities such as Iquitos and even as far downstream as Colombia. The rich history, diverse indigenous heritage, and strategic economic significance make Pevas an integral part of the Amazonian landscape. Its location at the mouth of the Ampiyacu River not only positions it as a key trading hub but also highlights its cultural and historical relevance in the Peruvian Amazon.
