The Harmandir Sahib and informally referred to as the "Golden Temple", is the holiest Sikh gurdwara located in the city of Amritsar, Punjab, India. The city was founded in 1574 by the fourth Sikh guru, Guru Ram Das. The Harmandir Sahib was designed by the fifth guru, Guru Arjan, who had the cornerstone laid by the Muslim Sufi saint Sai Hazrat Mian Mir on 28 December 1588. Guru Arjan completed the Adi Granth, the holy scripture of Sikhism, in 1604 and installed it in the gurdwara.
There are four doors to get into the Harmandir Sahib, which symbolise the openness of the Sikhs towards all people and religions. The present-day gurdwara was rebuilt in 1764 by Jassa Singh Ahluwalia with the help of other Sikh Misls. In the early nineteenth century, Maharaja Ranjit Singh secured the Punjab region from outside attack and covered the upper floors of the gurdwara with gold, which gives it its distinctive appearance and its English name.
The Harimandir Sahib is considered holy by Sikhs. The holiest text of Sikhism, the Guru Granth Sahib, is present inside the gurdwara during daytime and the holy book goes for Sukhasan during the night time. Its construction was mainly intended to build a place of worship for men and women from all walks of life and all religions to come and worship God equally. Over 100,000 people visit the holy shrine daily for worship, and also partake in the free community kitchen and meal (Langar) that is a hallmark of all Sikh Gurudwaras.
