Situated in Rajnagar on the eastern bank of River Kamla, near Madhubani district of Bihar, Navlakha Palace, also known as Rajnagar Palace, is an ancient royal palace which is a popular heritage building in the region. Built by Maharaja Rameshwar Singh, the palace formerly boasted of well paved gardens, tinkering ponds, temple complexes and the like. However, it suffered major loss and extensive damage in 1934 when an earthquake hit it. It has never been repaired and currently lies in ruins. However, even then, it boasts of old world charm and brilliant architecture and still visited by tourists and locals frequently.
