Answer:
The correct answer is C. After the Great Mosque of Cordoba was converted into a church for the final time, pillars and arches were added and enhanced with colorful mosaics.
Explanation:
The Great Mosque is a unique architectural monument in the place where once stood the Visigothic church Vincent of Zaragoza, which was built on the foundations of a Roman temple. After the conquest of Cordoba in 711 by the Moors, a mosque was built.
The original church building was demolished and the construction of the mosque began. Around 780, Abd el-Rahman I used the marble columns of nearby Roman villas. However, these were too small to reach the correct height. This could still be achieved by applying a second arc. The mosque owes its unique construction to this.
Since the Christian reconquest of Cordoba in 1236, the mosque has been in use as the cathedral of the diocese of Cordoba, dedicated to the Assumption of the Virgin Mary. King Ferdinand III of Castile and Emperor Charles V had the church expanded and embellished. Various renovations have taken place over the centuries, so that nowadays both Moorish and Christian influences are clearly recognizable. Both the floor plan of a traditional mosque and the Latin cross for a cathedral can be found in the building.
Originally there were about 1200 columns in the prayer room. Charles V gave permission to the Bishop of Cordoba in 1523 to convert it into a cathedral. Architect Hernan Ruiz then designed a cathedral in the heart of the mosque, for which around 400 columns were removed.
