Shyamsundar Jiu Temple is a Vaishnavite temple at Khardaha, associated with Birbhadra Goswami, the son of Nityananda Mahaprabhu. The site belongs to the devotional history of the Hooghly-side towns north of Kolkata.
It is a worthwhile stop for travellers already exploring Barrackpore, Khardaha and the river towns, especially if your interest is Bengal's Vaishnavite tradition rather than colonial-era monuments alone.
