The Darwaja’s of Ahmedabad were built during different times starting from 1411 as the entrances to the walled city of Ahmedabad. The Darwaja’s were built to protect the kingdom from the stranger’s attack. Due to which 21 gates were built to protect the city of Ahmed Shah from which it is named as Ahmedabad.
Ahmedabad was founded over the ancient settlement of Ashaval in 1411 by Ahmed Shah I of Gujarat Sultanate. He built the first citadel Bhadra Fort starting from Manek Burj, the first bastion of the city. The Bhadra Fort had eight gates excluding palace gates. When the city expanded, Ahmed Shah built the second fort which was later fortified by Mahmud Begada in 1486. The second fort had twelve major gates and other smaller gates. After arrival of railways, British built two more gates to facilitate the movement. Later the citywalls were demolished leaving the gates as monuments.
Most of the people do believe that there were 12 gates in Ahmedabad but according to some historian there were 16 gates. Later some Indologists found that Ahmedabad had 21 gates.
