The Castle of Viana do Alentejo is a gothic castle constructed during the reconquest and settlement of the central region of the Portuguese Alentejo, located in the parish of Viana do Alentejo, municipality of the same name. Although a relatively low-profile design, in comparison to its contemporaries, the structure served the period of strife associated with expansion of Portuguese forces/authority into the southern Algarve.HistoryThe castle was founded in 1313; on establishing a foral began a process of restoration and refurbishment in 1940, which included repairs to the battlements and walls. A return to this task occurred between 1970 and 1974, and again, in 1976, in addition to repairs to the towers.
