English: Golkonda consists of four distinct forts with a 10 km long outer wall with 87 semicircular bastions (some still mounted with cannons), eight gateways, and four drawbridges, with a number of royal apartments & halls, temples, mosques, magazines, stables, etc. inside. The lowest of these is the outermost enclosure into which we enter by the "Fateh Darwaza" (Victory gate, so called after Aurangzeb’s triumphant army marched in through this gate) studded with giant iron spikes (to prevent elephants from battering them down) near the south-eastern corner. At Fateh Darwaza can be experienced a fantastic acoustic effect, characteristic of the engineering marvels at Golkonda. A hand clap at a certain point below the dome at the entrance reverberates and can be heard clearly at the 'Bala Hisar' pavilion, the highest point almost a kilometre away. This worked as a warning note to the royals in case of an attack.
