The Golden Temple or Swarn Mandir or Harmandir Sahib is considered one of the holiest place by Sikhs. It was built by the fifth Sikh guru, Guru Arjan Dev, in the 16th Century. Guru Arjan Dev compiled and installed the holiest book – Adi Granth or GURU GRANTH SAHIB, here. There are four doors to get into the Harmandir Sahib, which symbolize the openness of the Sikhs towards all people and religions. The Harmandir Sahib also known as Swarn Mandir (The Golden Temple), is located in the city of Amritsar, India. In the 19th century, Maharaja Ranjit Singh covered the upper floors of the Gurdwara with gold, which gives it its distinctive appearance and its English name.
