The Taj Mahal is one of the most famous buildings in the world, the mausoleum of Shah Jahan's favourite wife, Mumtaz Mahal. It is one of the New Seven Wonders of the world, and one of the three World Heritage Sites in Agra. Agra is commonly identified as the "City of Taj".
Completed in 1653, the Taj Mahal was built by the Mughal king Shah Jahan as the final resting place for his beloved wife, Mumtaz Mahal. Finished in marble, it is one of India's many beautiful monuments and is set amidst landscaped gardens. Built by the Persian architect, Ustād 'Īsā, the Taj Mahal is on the south bank of the Yamuna River. It can be observed from Agra Fort from where Emperor Shāh Jahān gazed at it for the last eight years of his life, a prisoner of his son Aurangzeb. Verses of the Quran are inscribed on it and at the top of the gate are 22 small domes, signifying the number of years the monument took to build. The Taj Mahal was built on a marble platform that stands above a sandstone one. The most elegant dome of the Taj Mahal has a diameter of 60 feet (18 m), and rises to a height of 80 feet (24 m); directly under this dome is the tomb of Mumtaz Mahal. Shah Jahān's tomb was erected next to hers by his son Aurangzeb. The interiors are decorated with fine inlay work, incorporating semi-precious stones.
