Guru Arjan Dev was responsible for the construction of many public water tanks and buildings. In 1588, he planned to build a temple in the centre of the holy water tank called Amritsar or the pool of the nectar of immortality. As the temple was to be thrown open to people of all religions, castes, creeds and climes, he invited Mian Mir to lay the foundation stone of the Harmandir Sahib of Amritsar, the most sacred temple of Sikhs (now known worldwide as the Golden Temple). Mian Mir came to the city of Amritsar wearing a religious mendicant 's long cloak made up of patches of coarse wool and a cone - shaped cap, with a rose flower on top.
