The village grew around the Convento de Santo Antônio, built between 1658 and 1686 on the banks of the Paraguaçu near Iguape Bay. The convent is listed by IPHAN, Brazil's national heritage institute, but the building now stands in ruins. Its population of 1,261 in 2022, in 199 families, lives mainly from artisanal fishing and small family farming.

The village maintains its identity through artisanal fishing and small-scale farming that shape daily life for residents. These practices remain woven into the social fabric and connection locals have with the river.

The village is easy to explore on foot, with closely packed houses and open spaces along the water where you can observe local activity. Early morning is the best time to visit, when fishermen prepare their boats and the village is still quiet.

The Tupi name Paraguaçu joins pará (sea or large river) and gûasu (great), so it means "great sea" or "great river", referring to the Paraguaçu River. The village's full name pairs this with São Francisco. In 2022 the village had 1,261 inhabitants in 199 families, mostly artisanal fishers and small farmers.
