Qutub Minar's 50-yr-old doors being replaced over bat poop
The Archaeological Survey of India has started replacing wooden doors and windows of Delhi's Qutub Minar as the droppings of birds and bats, which enter the monument through the cracks, damage its stone. The repair works, which will cost â¹8 lakh, will be completed by later this month. The doors and windows were installed in the monument 50 years ago.
