Dighapatia Raj, Zamindari estate in Natore, Bangladesh

Dighapatia Raj is a zamindari estate seated at Dighapatia Palace, about 2.4 km from Natore town in Bangladesh. Raja Dayaram Roy built the main structure and some wings; Raja Pramada Nath Roy rebuilt the whole palace complex after the 1897 earthquake. The palace, also called Dighapatia Rajbari, now serves as Uttara Gano Bhaban, the official residence of Bangladesh's heads of state in North Bengal.

The Dighapatia Raj dynasty was founded by Dayaram Roy, who rose from a minor employee of the Natore rajas to diwan and received the title "Rai Rayan" from Nawab Murshid Quli Khan. He bought the Sah-Uziyal and other parganas at auction when Raja Ramkrishna Roy of Natore had to sell his zamindari. The family ruled for seven generations until the zamindari system was abolished in 1950.

Dayaram Roy, the dynasty's founder, established a chatuspathi (Sanskrit school) in Rajshahi and a math at the Rajbari, and installed the deities Krishnajiu, Govindajiu and Gopaljiu at Dighapatia Rajbari, granting them land and money for their worship. Prasannanath Roy built a dance hall and the 'Singhi Hall' at the palace, where festivals were held during Holi and Jhulan.

The estate is accessible by local transport from Natore, which lies about 50 kilometers from Rajshahi. Visitors should check current access rules beforehand, since the grounds now serve as an official government residence with restricted entry at times.

The palace was renamed Dighapatia Governor House on 24 July 1967 by Abdul Monem Khan, then Governor of East Pakistan. After independence, Sheikh Mujibur Rahman declared it Uttara Gonobhaban on 9 February 1972. President Ayub Khan had earlier resided there.
