This door (another photo courtesy of Rodney Olsen) is a door at the Taj Mahal in Agra, India. It defintely cannot be called a front door, but I though it's interesting to see a door on a less famous side of the Taj Mahal.
The Taj Mahal was built by a Muslim, Emperor Shah Jahan in the
memory of his dear wife and queen Mumtaz Mahal. It was constructed over a period of twenty-two years, employing twenty thousand workers. It was completed in the year 1648 at a cost of 32 MillionRupees. Its master architect was Ustad‘Isa, the renowned Islamic architect of his time. Expert craftsmen from Delhi, Qannauj, Lahore, and Multan were employed. In addition, many renowned Muslim craftsmen from Baghdad, Shiraz and Bukhara worked on many specialized tasks.
