Puerto Asis is a significant city in the Department of Putumayo in southern Colombia, with a history closely interwoven with the exploration of the Amazonian territories. Its foundation date is considered to be May 3, 1912, when Capuchin missionaries led by Father Estanislao de Las Corts established the first settlement here. The name of the city is deeply symbolic: the first part, "Puerto" (Port), indicates its function as a vital river port, while the second, "Asis," honors the birthplace of Saint Francis of Assisi, the patron saint of the missionary order.
A key role in the city's formation was played by its strategic location on the banks of the Putumayo River, a major tributary of the Amazon. This allowed the settlement to quickly transform into the main gateway to the southern Amazon and become an indispensable transport hub. The development of river navigation facilitated the active movement of cargo and passengers, connecting remote inland areas with the borders of neighboring nations.
In the early 20th century, the city's economy was based primarily on trade in the region's natural resources, particularly rubber and timber, which were floated down the river. Parallel to economic growth, the cultural landscape took shape: Catholic missions built schools and paved roads, introducing elements of the European way of life and Andean traditions to the local population.
