The Golden Temple, also known as Harmandir Sahib, is the landmark of Amritsar. It was built by Guru Arjan Dev, the fifth Sikh Guru, and completed in 1604. The temple's name comes from the gilding that covers most of the temple's exterior, which was done in the early 19th century. The temple is a symbol of the Sikh faith and its history, including the attempt to eradicate the Sikh religion by the Mughal emperor Aurangzeb, who had Guru Tegh Bahadur executed in 1675. Today, the Golden Temple is open to all visitors, regardless of their religion or caste.
