Later on the mosque again came into the hands of the Muslims in the year 1877. During the Mughal days the mosque housed some beautiful fountains and a huge central tank. But in 1857, after the Mutiny, British troops occupied the mosque and the soldiers left no stone unturned to damage the monument. They carved their names on the beautiful red sandstone walls.
