Qila Mubarak, a Historical National Monument of India, forms the heart of the city of Bathinda, in Indian Punjab. It has been in existence for approximately 1900 years in its current form. Some sources have the structure in its original, primitive form dating back to the Harrapa period.
It was here that Razia Sultan, the first woman to take charge of the Delhi throne was incarcerated on her defeat and dethroned. The bricks of the fort date back to the Kushana period when emperor Kanishka ruled over Northern India/Bactria. Raja Dab along with emperor Kanishka are believed to have built the fort.
