20. The Taj Mahal
Inspired to build the Taj Mahal while grieving his wife’s death, Shah Jahan used 28 types of jewels in the marble. It took over two decades to complete the construction of the building and cost 32 million rupees, which is about one million in American money today. It’s estimated that over 20,000 laborers worked on the project.
Today, the Taj Mahal is India’s most popular tourist attractions, with over 7 million visitors every year. Visitors are asked to respect the structure as a religious building because it is still used to prayer on Fridays.
