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:The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
