Half of charminar was covered in green sheets when we went to old city one day early last year. there was a lot of renovation work going on and it wqas really taking away from its beauty. its a beautiful place no doubt. stands majestically in the middle of the road and you cannot miss it if you are in the old city. the police station is right across and if you need to park, its available at the hospital nearby.
if you are deciding to go up charminar be ready to climb big and high steps spiralling up and down from the minarets.
