Although the origins of Alcázar de Toro castle date back to the 10th century, its current construction dates from the 15th century. Witness of important historical events, the Alcazar de Toro is one of the main buildings of the city.
After the división of León and Castile in the mid-12th century, Toro remained in the kingdom of León. In 1199 Alfonso 9th married Doña Berenguela and between 1188 and 1195 he started the construction of the castle and the walls. Sancho IV donated Toro its fortress to his wife, María de Molina, in 1283, and she rebuilt the old castle giving it the present structure. In the mid-19th century the castle was in ruins, having been used mostly to store gunpowder.References:
