During the ownership of Queen Santa Isabel, who died here in 1336, Estremoz became one of the main political centres of that reign, offering advice to important figures and being the private stage for royal politics during the end of the first dynasty.
At the beginning of the twentieth century the grouping of the castle, the village walls, the so called Torre das Couraças (Towers of Armour) and the Queen Santa Chapel were classified as a National Monument since 1910.
