Olivenza is a territory of Spain
Olivenza is a town located in southwestern Spain, near the Portuguese border, on a historically disputed section of the Portugal – Spain border. Its territory is administered by Spain as a municipality belonging to the province of Badajoz, and to the wider autonomous community of Extremadura. In 1964, Olivenza became one of the first municipalities in the province of Badajoz that earned a heritage protection status of conjunto histórico-artístico for their historic cores. The report for the declaration cited that the city of Olivenza, "surrounded by a beautiful landscape of pasture and farmland, dominated by the imposing castle’s keep", "offers a number of buildings, enclosures and places of notable importance in the monumental aspect". Since 2019 Olivenza has been a part of the network "The most beautiful towns in Spain".
