Hyderabad: A small part of Hyderabad’s historical Charminar’s minaret fell down on Wednesday night. This historical structure, which is more than 400 years old, and is made of limestone was being renovated by the Archeological Survey of India (ASI) over the last few months.

Officials of the ASI will be probing the issue on Thursday.

Last year, the National Thermal Power Corporation (NTPC) Ltd adopted the iconic Charminar under the Swachh Iconic Places Projects of India, a special drive under the Centre’s Swachh Bharat Mission.

NTPC Ltd and Greater Hyderabad Municipal Corporation (GHMC) had signed an MoU for implementation of development and beautification works under ‘Charminar Pedestrianization Project’ in Hyderabad.
