who constructed ibadat khana and for what purpose
Ibadat Khana The Ibādat Khāna (House of Worship) was a meeting house built in 1575 CE by the Mughal Emperor Akbar (r. 1556–1605) at Fatehpur Sikri to gather spiritual leaders of different religious grounds so as to conduct a discussion on the teachings of the respective religious leaders.[1]
Kashi Vishwanath Temple The temple has been mentioned in the Puranas including the Kashi Khanda (section) of Skanda Purana. The original Vishwanath temple was destroyed by the army of Qutb-ud-din Aibak in 1194 CE, when he defeated the Raja of Kannauj as a commander of Mohammad Ghori. The temple was rebuilt by a Gujarati merchant during the reign of Delhi's Sultan Iltutmish (1211-1266 CE). It was demolished again during the rule of either Hussain Shah Sharqi (1447-1458) or Sikandar Lodhi (1489-1517). Raja Man Singh built the temple during Mughal emperor Akbar's rule, but orthodox Hindus boycotted it as he had let the Mughals marry within his family. Raja Todar Mal further re-built the temple with Akbar's funding at its original site in 1585.[3]
