Ahmedabad (also spelled Ahmadabad) was establised by muslim ruller Sultan Ahmed Shah, ahmedabad is the sixth largest city (pop. 6.5 million) in India, and it's India's first UNESCO World Heritage City. It is the commercial hub of the state of Gujarat, though it is not the state capital, which is its twin city Gandhinagar, 30 km to the north. Although it is not very well known as a 'tourist' place, it is certainly worth a visit. Actually, the fact that there are fewer tourists will often get you a warmer welcome here. Also Gujaratis are known for their hospitality.
