Suppose The Taj Mahal is an ivory-white marble mausoleum on the south bank of the Yamuna river in the Indian city of Agra. It was commissioned in 1632 by the Mughal emperor Shah Jahan to house the tomb of his favorite wife, Mumtaz Mahal, and also houses the tomb of Shah Jahan himself. The Taj Mahal is considered one of the most beautiful buildings in the world and is a UNESCO World Heritage Site.
Can we infer that "The Taj Mahal was built as a fort."?
