The Sistine Chapel ceiling was completed first. Michelangelo painted the ceiling of the Sistine Chapel between 1508 and 1512. The Taj Mahal, on the other hand, was constructed later, with its construction beginning in 1632 and completing in 1653. The Sistine Chapel ceiling, with its iconic frescoes, predates the construction of the Taj Mahal, a symbol of love and one of the world's most renowned architectural beauties. Therefore, the Sistine Chapel ceiling predates the Taj Mahal by over 120 years.
