The Golden Temple is considered holy by Sikhs because the eternal guru of Sikhism, the Sri Guru Granth Sahib, is always present inside in it and its construction was mainly intended to build a place of worship for men and women from all walks of life and all religion to come and worship God equally.
The Sri Guru Granth Sahib is the holiest literature in the Sikh religion , the tenth guru of Sikhism, Guru Gobind Singh, on 7 October 1708 at Nanded made it the eternal Sikh Guru and the leader of Sikhism. Anywhere in the world where the Guru Granth Sahib is present is equally holy and precious to Sikhs. Amritsar is the location of Harmandir Sahib.
