The Harmandir Sahib, or as it is popularly known, the Golden Temple, was built between 1585 and 1604 AD, in Amritsar, India.
The temple is made of white marble, embellished with real gold–hence the name Golden Temple. Considered to be the holiest Gurudwara by the Sikhs, the Golden Temple was built so as to create a place of worship for people from all walks of life and all religions. This is reinforced by the fact that the temple has 4 entrances that open from all four directions.
Amazing Fact: 1,00,000 people visit the temple on a daily basis; many of them also participate in the community kitchen (langar).
