@pennsif Sir,
After Sonarga became the capital of Bengal in the Middle Ages, the British took control of Bengal and the Muslims here took steps to reduce the influence of the residents here as they did not get along with the British. At that time, the upper-caste Hindus who cooperated with the British lived there. As a result, the position of Hindu traders gradually developed. At the same time, those who did not cooperate with the British in business were forced to leave this area. As a result, various areas of Panam Nagar were destroyed. Currently, the houses on both sides of Panam Nagar Road were built with the help of the British and were built by Hindu upper-caste traders. After the British left, everything of these traders decreased, so the buildings gradually started to be abandoned.
