Mughal Emperor Shahjahan built the Taj Mahal in 1630 AD to enshrine the mortal remains of his beloved Queen Mumtaz Mahal. Taj Mahal manifests the wealth and luxury of Mughal art as seen in architecture and garden design, painting, and calligraphy. The 144 foot double dome of the Taj is capped with a finial and the four minarets each 131 ft high and crowned by an open octagonal pavilion highlight the perfect symmetry of the tomb. The filigree screen, meant to veil the area around the royal tomb was carved out of single block of marble. The Mughals believed that flowers were the symbols of the divine realm, thus in the Taj, pietra dura has been extensively used to translate naturalistic forms into decorative patterns that complement the majesty of its architecture. The monument changes with light and presents different times of the day.
