Approximately equidistant from the towns of Évora and Beja, the castle stands on the southern foot of Mount Saint Vincent, in a dominant position on the old part of the village.

It is considered, along with the Castle of Alvito, one of the most remarkable fortified architectural ensembles of the late Gothic period. Your name, Viana do Alentejo, binds to the noble title of the Meneses family, First Count of Viana, who stood out in the Portuguese campaigns of Morocco in the fifteenth century.
