The Taj Mahal, Agra, India

Dedicated to his late wife, Shah Jahan’s Taj Mahal is beautiful not only for its mesmerising marble facade. Their love story is one of bittersweet tragedy: Mumtaz Mahal ('the Jewel of the Palace') died while giving birth to their 14th child, so the emperor vowed never to marry again and promised he would build her the finest mausoleum ever seen.
