Urban II

Guibert or Wibert of Ravenna (c. 1029 – 8 September 1100) was an Italian prelate, archbishop of Ravenna, who was elected pope in 1080 in opposition to Pope Gregory VII and took the name Clement III. Gregory was the leader of the movement in the church which opposed the traditional claim of European monarchs to control ecclesiastical appointments, and this was opposed by supporters of monarchical rights led by the Holy Roman Emperor. This led to the conflict known as the Investiture Controversy. Gregory was felt by many to have gone too far when he excommunicated the Holy Roman Emperor Henry IV and supported a rival claimant as emperor, and in 1080 the pro-imperial Synod of Brixen pronounced that Gregory was deposed and replaced as pope by Guibert.

Consecrated as Pope Clement III in Rome in March 1084, he commanded a significant following in Rome and elsewhere, especially during the first half of his pontificate, and reigned in opposition to four successive popes in the anti-imperial line: Gregory VII, Victor III, Urban II, and Paschal II. After his death and burial at Civita Castellana in 1100 he was celebrated locally as a miracle-working saint, but Paschal II and the anti-imperial party soon subjected him to damnatio memoriae, which included the exhuming and dumping of his remains in the Tiber. He is considered an anti-pope by the Roman Catholic Church.

The Primatial Metropolitan Cathedral of Saint Mary of the Assumption (Spanish: Catedral Primada Metropolitana de Santa María de la Asunción), is a Roman Catholic cathedral in Toledo, Spain. It is the seat of the Metropolitan Archdiocese of Toledo. Since 1088, it holds the honorific title of Primatial, granted by Urban II, establishing a higher rank over the rest in the Iberian Peninsula.

The cathedral of Toledo is one of the three 13th-century High Gothic cathedrals in Spain and is considered, in the opinion of some authorities, to be the magnum opus of the Gothic style in Spain. It was begun in 1226 under the rule of Ferdinand III, and the last Gothic contributions were made in the 15th century when, in 1493, the vaults of the central nave were finished during the time of the Catholic Monarchs. It was modeled after the Bourges Cathedral, although its five naves plan is a consequence of the constructors' intention to cover all of the sacred space of the former city mosque with the cathedral, and of the former sahn with the cloister. It also combines some characteristics of the Mudéjar style, mainly in the cloister, with the presence of multifoiled arches in the triforium. The spectacular incorporation of light and the structural achievements of the ambulatory vaults are some of its more remarkable aspects. It is built with white limestone from the quarries of Olihuelas, near Toledo.
