Golconda Fort is an historic place in Hyderabad. The Fort was anciently built By the late Nizams for their stay in Hyderabad. The major speciality of the Golconda Fort is that when someone will clap or do some sound at the ground, that sound can be heard in the Rajmahal which is at the top of the Fort i.e. Nizam's personnel, and one of mysterious route from underground is also there for escape from enemies and this route will be up-to Charminar.
Nice. Golconda fort is one of the more interesting forts in India, with various security measures which make you wonder how cleaver the engineers of yesteryears were. I really like the last photo.
