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 Odeon of Herodes Atticus is a stone theatre structure located on the southwest slope of the Acropolis of Athens. It was built in 161 AD by the Athenian magnate Herodes Atticus in memory of his wife, Aspasia Annia Regilla. It was originally a steep-sloped theater with a three-story stone front wall and a wooden roof made of expensive cedar of Lebanon timber. It was used as a venue for music concerts with a capacity of 5,000. It lasted intact until it was destroyed and left in ruins by the Heruli in 267 AD.
The audience stands and the orchestra (stage) were restored using Pentelic marble in the 1950s. Since then it has been the main venue of the Athens Festival, which runs from May through October each year, featuring a variety of acclaimed Greek as well as International performances.
