Legend has it that this relic arrived in Portugal in the possession of Princess Vataça Lascaris, and today is (and on exhibition at the Royal Treasury in the Basilica of Castro Verde).

There are only three settlements in this parish, two of which are equidistant from the E1 motorway (Aviados and Casével) and the other (Estação de Ourique) which is a railway terminus and rural agglomeration.

The principal activities in the village are related to agriculture and animal husbandry, in addition to small commercial and industrial sectors associated with milling, electricians and saw-milling.

The village of Casével is home to acclaimed coral groups which have a long history of cultural importance within the municipality of Castro Verde.

The Associação de Cante Alentejano: Vozes das Terras Brancas is the central body that promotes various groups of traditional canto singers, including Vozes de Casével and Antigas Mondadeiras, and its installations are open to the public (in the main square), allowing visitors to listen and appreciate the traditional ethnography and food of the parish.
