Final answer:
The Taj Mahal was built using materials like white marble, red sandstone, and precious gemstones. The Great Mosque of Cordoba was converted into a church by adding Christian elements and altering the interior.
Step-by-step explanation:
The Taj Mahal, a memorial tomb for Shah Jahan's favorite wife who died young, was built using materials such as white marble, red sandstone, and precious gemstones. The main building material, white marble, was sourced from the Makrana mines in Rajasthan, India. The use of marble not only added to the grandeur and beauty of the Taj Mahal but also symbolized purity and eternity.
When the Great Mosque of Cordoba was converted into a church, several characteristics were added and enhanced. Christian elements such as the altar, choir stalls, a nave, and a sanctuary were introduced. The mihrab, which originally indicated the direction of prayer in Islam, was replaced with a Christian altar. The interior of the mosque was altered with the addition of a cathedral and other Christian architectural elements.
