Montalvão was an important settlement in Alto Alentejo in the early days of the Portuguese monarchy. The need to protect this sector of the border, combined with the ineffective population presence, determined that the locality was established as the seat of a vital territory for the survival of the Christian order. in the region. No wonder, therefore, that it was Commendation of the Order of Christ, an institution that would have been at the origin of the castle that generally comes down to us. Its construction has been pointed out in the reign of D. Dinis, but the monument still lacks from a broader archaeological study that allows conclusions to be drawn about the phases of occupation it went through. as having only one wall, without any attached tower, with access to the intramural space through a single door. This entrance was rebuilt a century later, certainly for a long time.
