Id like to get some information of Chennai if possible 
 It was formally known as Madras. It i the capital cit of the Indian state of Tamil Nadu. It is one of the few Indian cities that are a home to a diverse population of people without a common religious background. 
 Thats so nice can you tell me more about their demographics 
 Speaking of religion, there was a census that is done. And in 2011 it was found that 80.7 percent were hindu 9.5 muslim 7.7 christian, just to name a few . 
 Hinduism is such a peaceful religion. Do they have an official language there 
 They Speak mostly Tamil. Also it is the most visited Indian city by tourist. 
 Cool with it being a touristy place do they have fascinating architecture 
 They have various styles, such as the PALLAVAS, THE CHOLAS, and THE VIJAYANGARA EMPIRES. 
 are those historical building from ancient empires? 
 I am not sure about that. But I can give you some examples , The High court, Southern Railway and Senate house of the University of Madras. 
 does it tell you what makes these buildings so special 
 Sorry I do not know that information.. I have a bit of history for you. By the 189th century, the British had conquered most of the region around the Tamil Nadu. 
 Thank you for the lesson Have a great day! 
 You as well.
