The most extravagant monument ever built for love, it was constructed by Mughal emperor Shah Jahan as a memorial to his queen Mumtaz Mahal, made out of white marble took 22 years to complete (1630-1652 AD). Ustad Ahamad Lahori, a Persian Architect, is said to be the main designer and planner for this magnificent memorial. On full moon nights, the glory of the Taj is at its best. Legend has it that once the construction was completed, Shah Jehan had Lahori's hands cut off and his eyes gouged out, so he would never be able to duplicate the structure.
