Golconda Fort, Originally Mangaladevi Temple, discovered in 1080 CE

The name Gollakonda is derived from Telugu words Golla (Yadav) + Konda (Fort).
Golconda Fort History

The original temple of Goddess Mangala must have been built (or rebuilt) parallelly with Mangala Devi temple in Mangalore, during 9th century CE.
This was the era of Matsyendranath, the founder of the Nath tradition.
Original Mangala Devi temple is believed to be built by Sage Parasurama in Kerala style architecture, which is common in all temples in the South Indian state of Kerala and Western Ghats.
Mangalore was named after the goddes Mangaladevi, the presiding deity of the temple or a synonym of Tara Bhagvati of the Vajrayana Buddhist sect, who is same as Taara from Dasamahavidyas.
Worship of Taara in the form of Mangala was popular in South India. Due to this, women were named Mangala, Tara or Taramati. Seventh Sultan of Golconda, Abdullah Qutb Shah’s favorite courtesan was Taramati, who was behind the name sarai Taramati Baradari.

The fort was rebuilt and strengthened by Rani Rudrama Devi and her successor Prataparudra. After many year the fort came under the control of the Musunuri Nayaks, who defeated the Tughlaqi army occupying Warangal. It was ceded by the Musunuri Kapaya Nayak to the Bahmani Sultanate as part of a treaty in 1364 CE.
From Bahamani Sultans, Golconda fell into Sultan Quli’s hands, who formally became independent in 1538 CE and formed Qutb Shahi dynasty.
Qutb Shahis expanded the fort, whose 7 kilometres (4.3 miles) outer wall enclosed the city.
The fort finally fell into ruin in 1687 CE, after a year long siege leading to its fall at the hands of the Mughal emperor Aurangzeb.
