I want to know the answer to the following question:
What is the oldest piece of Qutb Shahi architecture in Hyderabad?
All the background I'm provided with is that "The Charminar, Qutb Shahi tombs and Golconda fort are considered to be monuments of national importance in India; in 2010 the Indian government proposed that the sites be listed for UNESCO World Heritage status.:11–18". Is that enough to answer the question?
Answer: no
