Maharaja Nabakrishna Deb (1733–97), founder of the Shobhabazar Rajbari royal family (at 35), started life as a modest aristocrat but soon amassed enormous wealth in his service to the British, in particular by his role in assisting to topple Siraj ud-Daulah.

The palace at 35 Raja Nabakrishna Street (known as Shobhabazar Rajbari or "Baag ola Bari - Palace with the lions"), on the northern side of the road, was the one first constructed by him, subsequently inherited by his adopted son from his elder brother Gopimohan and his descendants including his son Raja Radhakanta Deb.

the double storey wings on either side of the courtyard connect the thakurdalan with the naach ghar to the south.

A set of eight massive Tuscan columns support a wide projecting cornice at roof level.

Two rows of multifoliate arches at the northern end provide access to the nabaratna temple at the rear.
