Topped by golden domes, this handsome white-marble gurdwara was constructed at the site where the eighth Sikh guru, Harkrishan Dev, stayed before his death in 1664. Despite his tender years, the six-year-old guru tended to victims of Delhi’s cholera and smallpox epidemic, and the waters of the gurdwara tank are said to have healing powers. Sikh pilgrims flock here at all hours, and devotional songs waft over the compound, adding to the contemplative mood.
