Oeiras it originates from a chapel founded in 1695 and dedicated to Nossa Senhora da Vitória.
The village of Oeiras was elevated to town and county seat in 1712. It became the capital of Piauí in 1759, being elevated to municipality in 1761. It was capital until 1851.
The first settlers who entered the sertões of the current state of Piauí settled on the banks of the Mocha River, where the village that would give rise to Oeiras was formed, 320 kilometers from Teresina and 280 kilometers from São Raimundo Nonato.
Oeiras is a pilgrimage point for the faithful on various religious dates.
The traditional Semana Santa, the largest religious festival in the region, attracts people from various regions of Piauí, providing a unique spectacle of faith and popular religiosity.
The Bom Jesus do Passos Procession, the Fogaréu Procession and the Descent of the Cross are one of the most significant events in the First Capital.
Not to mention the Cultural Expressions of its Folklore and Culture, including the Congos do Rosário, considered one of the most beautiful Afro-Brazilian expressions.

In Oeiras, a chapel made of wood and clay was built in 1697, later replaced by the church of Nossa Senhora da Vitória, whose works were completed in 1733.
The church, today listed as a national heritage, still survives in the small town, which preserves in its narrow streets a beautiful house. The procession of Bom Jesus dos Passos, which gathers crowds of faithful during Holy Week, also dates back to the origins of Oeiras.
The event is an opportunity to watch the traditional mandolin players of the city, who roam the streets with their instruments.
At other times of the year, visitors may – with luck – come across some of them carelessly strumming their mandolins in the square, on a Saturday or Sunday afternoon: a scene of rare charm.
SAINT RAIMUNDO NONATO
The city's residents are proud to call it the “capital of prehistory”.
It makes sense: the gateway to the Serra da Capivara National Park, São Raimundo Nonato lives off tourism and activities related to the conservation of the place.
Here, as in the entire region, the seasons are well defined – there is the dry period, between May and November, when the vegetation loses its leaves and takes on light gray tones, and the rainy months, between December and May, when everything green.
It is during the dry season that the most important events in the municipality take place: the patron saint's party, in August, when the city is filled with flags, and the Serra da Capivara International Festival, in September, with music, theater and plastic arts shows. from various parts of the world.
Reaching São Raimundo Nonato is an arduous task: from Teresina, the route is 540 kilometers, along BR-316, BR-343 and PI-140, followed by BR-324.
For those coming from Petrolina, in Pernambuco, take the BR-235 to Remanso and then the BR-324. The route, of 300 kilometers, has stretches of road in a precarious state of conservation.
