Gurdwara Mardon Sahib Patshahi 9 & 10 - Mardon is an old Village, 15 kilometres south of Ambala City along the Ambala-Barnala road. It was visited both by Guru Tegh Bahadur and by Guru Gobind Singh. According to Mahan Kosh, separate Shrines dedicated to the two Gurus existed near the Village, but now a common Gurdwara Mardon Sahib Patshahi 9 ate 10 has been established on the right bank of the river Tangari where approach road to the Village branches off from the main Ambala-Barnala road. The Gurdwara owns 120 acres of land; the Gurdwara complex therefore, also includes the vast farmhouse. Like the old Shrines near the Village, there are separate sanctums for the two Gurus. The one dedicated to Guru Tegh Bahadur comprises a square domed room, where Guru Granth Sahib is seated, and the adjoining divan-hall. A separate low-domed small room is in the memory of Guru Gobind Singh. Guru Granth Sahib is seated here also.

Gurudwara Mardoun Sahib is situated in the Viallge Bhanokheri Distt Ambala. Guru Tegh Bahadur stayed for two nights. During his stay he did preaching on Sikhism. Guru Tegh Bahadur blessed the king with a son, when he requested for the same. After getting this blessing King dontated a huge portion of land on Guru's name. Guru Tegh Bahadur also blessed this place that who so ever visits here with Devotion and dedicateion his or her wishes will be granted.

Guru Gobind Singh spent almost 6 months and used ot play Hockey with his peers. He used to spent his his afternoons here as one of his hockey grounds was mantained here and other was in the Village BhanoKheri, where now days Gurudwara Gendsar Sahib is located.
