Map of old Ahmedabad in 1855

The Historic City of Ahmadabad or Old Ahmedabad, the walled city of Ahmedabad in India, was founded by Ahmad Shah I of Gujarat Sultanate in 1411. It remained the capital of the Gujarat Sultanate and later important political and commercial centre of Gujarat. Today, despite having become extremely crowded and dilapidated, it still serves as the symbolic heart of metropolitan Ahmedabad. It was inscribed as the World Heritage City by UNESCO in July 2017.
