Guru Ram Rai Darbar Sahib is a Sikh place of worship in Dehradun, India, dedicated to Baba Ram Rai, eldest son of Guru Har Rai, the seventh of the ten Sikh Gurus. Baba Ram Rai settled here with his followers in the mid-17th century, after he was banished by the Sikh orthodoxy for mistranslating scripture in front of the Mughal emperor Aurangzeb, so as to not cause offence. It is believed the city, Dehradun, gets its name from the religious camp established by him: a "dera", or camp, in the "doon" valley. Read more on Wikipedia
