Agra
Completed in 1653, the Tāj Mahal was built by the Mughal king Shāh Jahān as the grave for his beloved wife, Mumtāz Mahal. It was built in white marble. It is perhaps India's most fascinating and beautiful monument. This perfectly symmetrical monument took 22 years (1630-1652) of hard labour and 20,000 workers, masons and jewellers to build. Along with the building there is landscaped gardens. The architect who built the monument is named Persian architect, Ustād 'Īsā. The Tāj Mahal is located on the bank of the Yamuna River which can be observed from Agra Fort.
