The origin of the civil parish is based in the construction, on the eastern part of the walled settlement, of the first parochial church in 1300 by Diocesano, Bishop of Évora.

[2][3] Between the 14th and 16th century the area around the church was occupied by residences and food cellars that collected the land rents of the region.

[2][3] In 1534, the Cardinal Infante Afonso, bishop of Évora, ordered the reconstruction of the church, including its Manueline era portico (which was historically incorporated into the local logotypes).

[2] Since its early inception, from outside the walls, an arch of constant development occurred along the accessways that afforded the best conditions and water supplies.

[2] In 1843, with the expulsion of the religious orders by the Liberal regime, the parish seat was transferred to the Convent of São João de Deus, before being transformed into a civic administration.
