Charminar is as much the signature of Hyderabad as Taj Mahal is of Agra or Eiffel Tower is of Paris. Mohammed Quli Qutb Shah, the founder of Hyderabad, built Charminar in 1591 at the centre of the original city layout. It is believed to have been built as a charm to ward off a deadly epidemic raging at that time. Four graceful minarets soar to a height of 48.7m. Charminar has 45 prayer spaces and a mosque in it.
