Jor Bangla Mandir, also called Keshta Rai Mandir, has a typical architecture that is found in the southern part of Bengal. The temple was built by Malla King Raghunath Singha Dev I in 1655 CE. The structure resembles two traditional ‘do-chala’ village huts put together side by side. One of them serves as a porch and the other, which is behind the former, serves as a shrine. The curved roof of this pair of huts is surmounted by a ‘char-chala sikhara’.
The walls are decorated mostly with terracotta panels describing scenes from the Ramayana and the Mahabharata along with floral and geometrical patterns. The rich details narrate the whole story visually.
