Gurdwara Sahib Kolayat - Kolayat, an ancient town in Bikaner district, is linked to the district town, 52 kilometres away to the northeast of it, by rail and road. It is known for an Hindu temple dedicated to Kapil Muni. Guru Nanak Dev and Guru Gobind Singh visited Kolayat. It was here that Bhai Daya Singh and Dharam Singh rejoined Guru Gobind Singh after delivering the Guru's admonitory letter, Zafarnama to Emperor Aurangzeb at Ahmadnagar. There being no Sikh population at Kolayat, no memorial or Shrine was set up in honour of the Guru's visit until 1968, when some Sikh colonizers lately settled in the area constructed Gurdwara Sahib Kolayat in a single room near the bank of an artificial lake northeast of the town. It is served by a Sikh farmer whose farmhouse-cum-residence is close by Sikhs from nearby Villages and farmhouses assemble here to celebrate the birth anniversaries of Guru Nanak Dev and Guru Gobind Singh.
