from the Mughal Empire in 1724 until 1948, when the Indian integration of Hyderabad occurred. The siege of Golconda occurred in January 1687, when Mughal Emperor Aurangzeb led his forces to besiege the Qutb Shahi dynasty at Golconda fort (also known as the Diamond Capitol of its time) and was home to the Kollur Mine. The ruler of Golconda was the well entrenched Abul Hasan Qutb Shah. The fort Golconda fort is listed as an archaeological treasure on the official "List of Monuments" prepared by the Archaeological Survey of India under The Ancient Monuments and Archaeological Sites and Remains Act. Golconda consists of four distinct forts with a long outer wall with 87 semicircular bastions (some still mounted with cannons), eight gateways, and four drawbridges, with a number of royal apartments and halls, temples, mosques, magazines, stables, etc. inside. The lowest of these is the outermost enclosure entered 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. An acoustic effect can be experienced at Fateh Darwazaan, 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 kilometer away. This worked as a warning in case of an attack. Bala Hissar Gate is the main entrance to the fort located on the eastern side. It has a pointed arch bordered by rows of scroll work. The spandrels have yalis and decorated roundels. The area above the door has peacocks with ornate tails flanking an ornamental arched niche. The granite block lintel below has sculpted yalis flanking a disc. The design of peacocks and lions is typical of Hindu architecture and underlies this fort's Hindu origins. Jagadamba temple, located next to Ibrahim mosque and the king's palace, is visited by lakhs of devotees during Bonalu festival every year. Jagadamba temple is about 900 to 1,000 years old, dating back to early Kakatiya period. A Mahankali temple is located in the vicinity, within Golconda fort. Toli Masjid, situated at Karwan, about from the Golconda fort, was built in 1671 by Mir Musa Khan Mahaldar, royal architect of Abdullah Qutb Shah. The facade consists of five arches, each with lotus medallions in the spandrels. The central arch is slightly wider and
