This is the biggest mosque in Hyderabad and lies within hundred yards to the southwest of Charminar. The name is derived from the Grand Mosque at Mecca on which it is patterned. The hall measures 67 mt. by 54 mt. and is 23 mt. in height. Fifteen arches, five on each of the three sides, support the roof. A high wall to provide the Mehrab blocks the western side.

At each end are two huge octagonal columns made out of a single piece of granite each topped by an arched gallery that is crowned by a dome. The mosque is one of the largest in India and can accommodate ten thousand people at a time.
