Taj Mahal is regarded as one of the eight wonders of the world, and some Western historians have noted that its architectural beauty has never been surpassed.  The Taj Mahal is the most beautiful monument built by the Mughals, the Muslim rulers of India. Taj Mahal is built entirely of white marble. Its stunning architectural beauty is beyond adequate description, particularly at dawn and sunset.  The Taj seems to glow in the light of the full moon.  On a foggy morning, the visitors experience the Taj Mahal as if suspended when viewed from across the Jamuna River. Muslim, Emperor Shah Jahan in the memory of his dear wife and queen built the Taj Mahal in Agra, India. The society at the time was very productive and created a lot of success and hope for the Indians there.  When Mumtaz Mahal was still alive, she extracted four promises from the emperor:  first, that he build the Taj Mahal; second, that he should marry again; third, that he should be kind to their children; and fourth, that he visit the tomb on her death anniversary.  He kept the 1st and 2nd promises.  The construction began in 1631. The expert craftsman from Delhi, Qannauj, Lahore, and Multan were employed. They constructed the monument over a period of twenty-two years, with the employment of 20,000 workers. The total amount spent on the beautiful and sacred monument was 32 million rupees. The problems and issues of the Taj Mahal were very difficult back then.  Actually, it was two main issues, but they were very burdensome.  The only issue was the death of his wife and getting the beautiful monument done. The lengthy wait and the overcoming of her death were too much for Shah Jahan, but he had promised to his loving wife that he would eventually complete the sacred monument in her name.
