who built the red fort and the jama masjid in delhi
Jama Masjid, Delhi Mughal emperor Shah Jahan built the Jama Masjid between 1644 and 1656. It was constructed by more than 5000 workers. It was originally called Masjid-i-Jahan-Numa, meaning 'mosque commanding view of the world'. The construction was done under the supervision of Saadullah Khan, wazir (or prime minister) during Shah Jahan's rule. The cost of the construction at the time was one million Rupees.[1] Shah Jahan also built the Taj Mahal, at Agra and the Red Fort in New Delhi, which stands opposite the Jama Masjid. The Jama Masjid was completed in 1656 AD (1066 AH).[1] The mosque was inaugurated by an Imam Bukhari, a mullah from Bukhara, Uzbekistan, on 23 July 1656, on the invitation from Shah Jahan.[2] About 25,000 people can pray in the courtyard at a time and it is sometimes regarded as India's largest mosque.[3][4] The mosque is commonly called "Jama" which means Friday.[1]
Qutb Minar Qutab Minar was established along with Quwwat-ul-Islam Mosque around 1192 by Qutab-ud-din Aibak, first ruler of the Delhi Sultanate.[4] The mosque complex is one of the earliest that survives in the Indian subcontinent.[6][7] The minaret is named after Qutab-ud-din Aibak, or Qutbuddin Bakhtiar Kaki, a Sufi saint.[8] Its ground storey was built over the ruins of the Lal Kot, the citadel of Dhillika.[9] Aibak's successor Iltutmish added three more storeys.[8] The minar's topmost storey was damaged by lightning in 1369 and was rebuilt by Firuz Shah Tughlaq, who added another storey. In 1505, an earthquake damaged Qutub Minar; it was repaired by Sikander Lodi. On 1 September 1803, a major earthquake caused serious damage. Major Robert Smith of the British Indian Army renovated the tower in 1828 and installed a pillared cupola over the fifth story, thus creating a sixth. The cupola was taken down in 1848, under instructions from The Viscount Hardinge, then Governor General of India. It was reinstalled at ground level to the east of Qutab Minar, where it remains. It is known as "Smith's Folly".[10]
