Catedral de Toledo, Spain

For many years, an unwritten popular tradition has held that there was originally a church from the era of the first Archbishop Eugene (Saint Eugene of Toledo) located in the same place as the present cathedral. This church was consecrated for a second time in the year 587, after having undergone some alterations, as testified by a 16th-century inscription preserved on a pillar in the rear of the nave of the church which states:
In the name of the Lord the Church of Saint Mary was consecrated as Catholic, the first day of the ides of April, in the joyful first year of the reign of our most glorious king Flavius Reccared, Era 625 [13 of April of 587].
The city of Toledo was reconquered by Alfonso VI, King of León and Castile, in 1085. One of the points of the Muslim capitulation that made possible the transfer of the city without bloodshed was the king’s promise to conserve and respect their institutions of higher learning, as well as the customs and religion of the Muslim population which had coexisted with the larger Mozarabic population. Naturally, the preservation of the main mosque was integral to this compromise. Shortly thereafter, the king had to depart on matters of state, leaving the city in charge of his wife Constance and the abbot of the monastery of Sahagún, Bernard of Sedirac (or Bernard of Cluny), who had been elevated to the rank of archbishop of Toledo. These two, in mutual accord and taking advantage of the absence of the king, undertook an unfortunate action which, as told by the priest Mariana in his General History of Spain, almost provoked a Muslim uprising and consequent ruin of the recently conquered city.
The structure of the building is greatly influenced by the French Gothic style of the 13th century, but adapted to Spanish taste. It measures 120 metres (390 ft) in length by 59 metres (194 ft) in width and 44.5 metres (146 ft) high. It consists of five naves with transept and double ambulatory. The outer naves present an odd anomaly in being a little wider than the other two. The oldest part of the building is the sanctuary, which maintains in its architecture the original triforia that extended along the length of the naves and were removed in one of the many alterations that the cathedral underwent. Still in the Gothic period, these triforia were replaced with large stained-glass windows. Those triforia that survive in the sanctuary are of Mudéjar influence. The lowest section is made of cusped arches that rest on paired columns and the upper section presents interlaced arches typical of Mudéjar. It is not known if these Mudéjar themes existed in the previous mosque and were copied as a reminder or if they were added in one of the improvements of the stonework, as something original and tasteful. read
