Darosh Bari Madrasa(দারস বাড়ি মাদ্রাসা) is possibly the oldest Madrasa(মাদ্রাসা) of Bangladesh. According to the inscription that was found at the vicinity of the madrasa(মাদ্রাসা) premise, it was built around 1500 AD, during the reign of Sultan Alauddin Hossen Shah. Now a days only few ruins are available. This archaeological edifice is located at the Chapainawabganj(চাপাইনবাবগঞ্জ) of Bangladesh.
This madrasa(মাদ্রাসা) is located at the other side of the pond of the Darosh Bari Mosque(দারস বাড়ি মসজিদ). This historical place is surrounded by dense mango forest. After visiting the mosque, you can easily visit this place within 10 minutes.
This dilapidated old edifice(renovated later) is having a shape of square. At the first look over the premise, it gave me an impression of Moynamoti Salbon Bihar(ময়নামতি শাল বনবিহার). When I was traveling there, possibly that was the hottest day from the month at Rajshahi. I have just given a cursory look around the place to avoid sweating.
This place is located almost near to the India-Bangladesh border. If you want to visit this place, just look at this article(Darosh Bari Mosque(দারস বাড়ি মসজিদ)).
