San Pedro de Cardeña Monastery was founded before 902. The prosperity of the monastery in the early medieval period is reflected in the quality of its scriptorium, in which the monk Endura performed extraordinary works. The Blessed of San Pedro de Cardeña was made between 1175 and 1180, has 290 pages and 51 miniatures.
The convent church dates from the 16th century; annexed is the Capilla del Cid, where the hero and some of his relatives were buried.
Some parts of Romanesque style have been preserved, the church being Gothic and part of the façade from the 18th century. Cistercian monks have lived here since 1942 and they make wine as well as medicinal herb liquors.
El Cid found refuge in this monastery during his exile, and he lived here together with his wife and daughters to the end of his days.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
