a Vishnu temple by some Hindus, and finally into the mosque by the Turks)
and the building at Ajmer called Arhai Din Ka Jhonpra (which had been a
monastery). The only new construction in the mosque in Delhi was a facade
of three elaborately carved arches in front of the deity room (garba-griha)
which was demolished.
    The most magnificent building constructed by the Turks (founded by
Aibak and completed by Iltutmish) in the 13th century was the Qutub Minar
at Delhi. The tower, standing at 71.4 metres was dedicated to the Sufi saint,
Qutub-ud-din Bakhtiyar Kaki. Although traditions of building towers are to
be found both in India and West Asia, the Qutub Minar is unique in many
ways. It derives its effect mainly from the skillful manner in which the
balconies have been projected yet linked with the main tower, the use of red
and white sand stone and marble in panels and in the top stages, and the
ribbed effect.
