On
the western side of the Taj Mahal is a mosque, made up of red sandstone.
Used for prayer purposes, the mosque faces the direction of the holy
city of Mecca. The boundary near the well of the Taj Mahal mosque has a
small stone enclosure, which housed the remains of Mumtaz Mahal before
they were interned in the mausoleum. Adorned with pietra dura on the
outside, the mosque in Taj Mahal of Agra, boasts of 4 octagonal towers
and 3 elegant domes. The sparkling floor is made up of a material that appears to be velvet red in shade and is covered with 539 prayer carpets. The interiors of the mosque are inscribed with delicate calligraphy citing the name Allah and quotations from scriptures. There is also a replica of the Masjid of the Taj Mahal of India, standing opposite to it. However, it was never used for prayer purposes.
