Sri Harmandir Sahib, also known as Sri Darbar Sahib or Golden Temple, (on account of its scenic beauty and golden coating for English speaking world), is the holiest shrine in Sikhism. It is located in the city of Amritsar, which was established by Guru Ram Das, the fourth guru of the Sikhs and is known as "guru di nagri" which means city of the Sikh Guru. The Sikhs all over the world, daily wish to pay visit to Sri Amritsar and to pay obeisance at Sri Harmandir Sahib in their Ardas. The Harmandir Sahib 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 7th 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. Its name literally means temple of God. The fourth Guru of Sikhism, Guru Ram Das, excavated a tank in 1577 AD which subsequently became known as Amritsar (meaning: Pool of the Nectar of Immortality), giving its name to the city that grew around it. In due course, a splendid Sikh edifice, Harmandir Sahib (meaning: The abode of God), rose in the middle of this tank and became the supreme centre of Sikhism. Its sanctum came to house the Adi Granth comprising compositions of Sikh Gurus and other saints considered to have Sikh values and philosophies e.g. Baba Farid, Kabir, etc. The compilation of the Adi Granth was started by the fifth Guru of Sikhism, Guru Arjan Dev. Sri Harmandir Sahib, is built on a 67ft. square platform in the centre of the Sarovar(tank). The temple itself is 40.5ft. square. It has a door each on the East, West, North and South. The Darshani Deori (an arch) stands at the shore end of the causeway. The door frame of the arch is about 10ft in height and 8ft 6inches in breath. The door panes are decorated with artistic style. It opens on to the causeway or bridge that leads to the main building of Sri Harmandir Sahib. It is 202 feet in length and 21 feet in width. The bridge is connected with the 13 feet wide 'Pardakshna' (circumambulatory path). It runs round the main shrine and it leads to the 'Har ki Paure' (steps of God). On the first floor of 'Har ki Paure', there is continuous reading of Guru Granth Sahib. The main structure of Sri Harmandir Sahib, functionally as well as technically is a three-storied one. The front, which faces the bridge, is decorated with repeated cusped arches and the roof of the first floor is at the height of the 26 feet and 9 inches. At the top of the first floor 4 feet high parapet rises on all the sides which has also four 'Mamtees' on the four corners and exactly on the top of the central hall of the main sanctuary rises the third story. It is a small square room and have three gates. A regular recitation of Guru Granth Sahib is also held there. On the top of this room stands the low fluted 'Gumbaz'(dome) having lotus petal motif in relief at the base inverted lotus at the top which supports the 'Kalash' having a beautiful 'Chhatri' at the end. Its architecture represents a unique harmony between the Muslims and the Hindus way of construction work and this is considered the best architectural specimens of the world. It is often quoted that this architecture has created an independent Sikh school of architecture in the history of art in India.
